Porting notes:
1. 13fe019870 introduced a merge conflict
in dsl_dataset_user_release_tmp where some variables were moved
outside of the preprocessor directive.
2. dea9dfefdd747534b3846845629d2200f0616dad made the previous merge
conflict worse by switching KM_SLEEP to KM_PUSHPAGE. This is notable
because this commit refactors the code, adding a new KM_SLEEP
allocation. It is not clear to me whether this should be converted
to KM_PUSHPAGE.
3. We had a merge conflict in libzfs_sendrecv.c because of copyright
notices.
4. Several small C99 compatibility fixed were made.

The dbufstat.py command was added to provide a conveniant way to
easily determine what ZFS is caching. The script consumes the
raw /proc/spl/kstat/zfs/dbufs kstat data can consolidates it in
to a more human readable form. This was designed primarily as
a tool to aid developers but it may also be useful for advanced
users who want more visibility in to what the ARC is caching.
When run without options dbufstat.py will default to showing a
list of all objects with at least one buffer present in the
cache. The total cache space consumed by that object will be
printed on the right along with the object type. Similar to the
arcstats.py command the -x option may used to display additional
fields.
Two other modes of operation are also supported by dbufstat.py
and the expectation is additional display modes may be added as
needed. The -t option will summerize the total number of bytes
cached for each object type, and the -b option will show every
dbuf currently cached.
The script was designed to be consistent with arcstat.py and
includes most of the same options and funcationality.

When creating a new pool, or adding/replacing a disk in an existing
pool, partition tables will be automatically created on the devices.
Under normal circumstances it will take less than a second for udev
to create the expected device files under /dev/. However, it has
been observed that if the system is doing heavy IO concurrently udev
may take far longer. If you also throw in some cheap dodgy hardware
it may take even longer.
To prevent zpool commands from failing due to this the default wait
time for udev is being increased to 30 seconds. This will have no
impact on normal usage, the increase timeout should only be noticed
if your udev rules are incorrectly configured.

Libraries that depend on other libraries should list them in ELF's
DT_NEEDED field so that programs linking to them do not need to specify
those libraries unless they depend on them as well. This is not the case
in the current code and the consequence is that anything that needs a
library must know its dependencies. This is fragile and caused GRUB2's
configure script to break when a dependency was added on libblkid in
libzfs.
This resolves that problem by using LIBADD/LDADD to specify libraries in
Makefile.am instead of LDFLAGS. This ensures that proper DT_NEEDED
entries are generated and prevents GRUB2's configure script from
breaking in the presence of a libblkid dependency. This also removes
unneeded dependencies from various files.

WARNING: This patch changes the user/kernel ABI. That means that

the 0.6.2 kernel modules. Ensure you load the matching kernel
modules from master after updating the utilities. Otherwise the
zfs/zpool commands will be unable to interact with your pool and

Remove the logging of the "release" operation in

function. I've got no idea why this particular code would have worked
in Illumos. This code has subsequently been completely reworked in

Add a missing call to fnvlist_free(nvl) in log_internal() that was added

This implements vdev_bdev_database_check(). It alters the detected
sector size of any device listed in a database of drives known to lie
about their physical sector sizes.
This is based on "6931570 Add flash devices' VID/PID to disk table to
advertising 4K physical sector size" from Open Solaris and on
sg_simple4.c from sg3_utils. About two dozen lines are taken from
sg_simple4.c, which is GPLv2 licensed. However, sg_simple4.c is
analogous to a Hello World program and is safe for us to use. We
requested that Douglas Gilbert, the author of sg_simple4.c, confirm that
this is the case. A cutdown version of his response is as follows:
```
I would consider a SCSI INQUIRY example using the Linux sg
driver interface (also written by me) as the equivalent of an
"hello world" program in C.
```
The database was created with the help of the freenode and ZFSOnLinux
communities.
Some notes:
1. The following drives both were confirmed to lie via reports in IRC
and they contain capacity information in their identifiers:
INTEL SSDSA2M080
INTEL SSDSA2M160
M4-CT256M4SSD2
WDC WD15EARS-00S
WDC WD15EARS-00Z
WDC WD20EARS-00M
The identifiers for different capacity models were extrapolated and
added under the assumption that those models also lie. Google was used
to verify that the extrapolated drive identifiers existed prior to their
inclusion.
2. The OCZ-VERTEX2 3.5 identifer applies to two drives that differ
solely in page size (and slightly in capacity). One uses 4096-byte pages
and the other uses 8192-byte pages. Both are set to use 8192-byte pages.
We could detect the page size by checking the capacity, but that would
unnecessarily complicate the code.
3. It is possible for updated drive firmware to correctly report the
sector size. There were reports of a few advanced format drives doing
that. One report stated that the vendor changed the identification
string while another was unclear on this. Both reports involved WDC
models.
4. Google was used to determine the size of pages in the listed flash
devices. Reports of 8192-byte pages took precedence over reports of
4096-byte pages.
5. Devices behind USB adapters can have their identification strings
altered. Identification strings obtained across USB adapters are
omitted and no attempt is made to correct for alterations made by USB
adapters when doing comparisons against the database. Two entries in the
Open Solaris database that appear to have been altered by a USB
adapter were omitted.

When calling mount(), care must be taken to avoid passing in flags
that are used only by the user space utilities. Otherwise we may
stomp on flags that are reserved for other purposes in the kernel.
In particular, openSUSE 12.3 kernels have added a new MS_RICHACL
super-block flag whose value conflicts with our MS_COMMENT flag. This
causes incorrect behavior such as the umask being ignored. The
MS_COMMENT flag essentially serves as a placeholder in the option_map
data structure of zfs_mount.c, but its value is never used. Therefore
we can avoid the conflict by defining it to 0.
The MS_USERS, MS_OWNER, and MS_GROUP flags also conflict with reserved
flags in the kernel. While this is not known to have caused any
problems, it is nevertheless incorrect. For the purposes of the
mount.zfs helper, the "users", "owner", and "group" options just serve
as hints to set additional implied options. Therefore we now define
their associated mount flags in terms of the options that they imply
rather than giving them unique values.

The vdev_file.c implementation in this patch diverges significantly
from the upstream version. For consistenty with the vdev_disk.c
code the upstream version leverages the Illumos bio interfaces.
This makes sense for Illumos but not for ZoL for two reasons.
1) The vdev_disk.c code in ZoL has been rewritten to use the
Linux block device interfaces which differ significantly
from those in Illumos. Therefore, updating the vdev_file.c
to use the Illumos interfaces doesn't get you consistency
with vdev_disk.c.
2) Using the upstream patch as is would requiring implementing
compatibility code for those Solaris block device interfaces
in user and kernel space. That additional complexity could
lead to confusion and doesn't buy us anything.
For these reasons I've opted to simply move the existing vn_rdwr()
as is in to the taskq function. This has the advantage of being
low risk and easy to understand. Moving the vn_rdwr() function
in to its own taskq thread also neatly avoids the possibility of
a stack overflow.
Finally, because of the additional work which is being handled by
the free taskq the number of threads has been increased. The
thread count under Illumos defaults to 100 but was decreased to 2
in commit 08d08e due to contention. We increase it to 8 until
the contention can be address by porting Illumos #3581.

NOTES: This patch has been reworked from the original in the
following ways to accomidate Linux ZFS implementation
*) Usage of the cyclic interface was replaced by the delayed taskq
interface. This avoids the need to implement new compatibility
code and allows us to rely on the existing taskq implementation.
*) An extern for zfs_txg_synctime_ms was added to sys/dsl_pool.h
because declaring externs in source files as was done in the
original patch is just plain wrong.
*) Instead of panicing the system when the deadman triggers a
zevent describing the blocked vdev and the first pending I/O
is posted. If the panic behavior is desired Linux provides
other generic methods to panic the system when threads are
observed to hang.
*) For reference, to delay zios by 30 seconds for testing you can
use zinject as follows: 'zinject -d <vdev> -D30 <pool>'

The PaX team modified the kernel's modpost to report writeable function
pointers as section mismatches because they are potential exploit
targets. We could ignore the warnings, but their presence can obscure
actual issues. Proper const correctness can also catch programming
mistakes.
Building the kernel modules against a PaX/GrSecurity patched Linux 3.4.2
kernel reports 133 section mismatches prior to this patch. This patch
eliminates 130 of them. The quantity of writeable function pointers
eliminated by constifying each structure is as follows:
vdev_opts_t 52
zil_replay_func_t 24
zio_compress_info_t 24
zio_checksum_info_t 9
space_map_ops_t 7
arc_byteswap_func_t 5
The remaining 3 writeable function pointers cannot be addressed by this
patch. 2 of them are in zpl_fs_type. The kernel's sget function requires
that this be non-const. The final writeable function pointer is created
by SPL_SHRINKER_DECLARE. The kernel's set_shrinker() and

The issue with hot spares in ZoL is because it opens all leaf
vdevs exclusively (O_EXCL). On Linux, exclusive opens cause
subsequent exclusive opens to fail with EBUSY.
This could be resolved by not opening any of the devices
exclusively, which is what Illumos does, but the additional
protection offered by exclusive opens is desirable. It cleanly
prevents you from accidentally adding an in-use non-ZFS device
to your pool.
To fix this we very slightly relaxed the usage of O_EXCL in
the following ways.
1) Functions which open the device but only read had the
O_EXCL flag removed and were updated to use O_RDONLY.
2) A common holder was added to the vdev disk code. This
allow the ZFS code to internally open the device multiple
times but non-ZFS callers may not.
3) An exception was added to make_disks() for hot spare when
creating partition tables. For hot spare devices which
are already opened exclusively we skip creating the partition
table because this must already have been done when the disk
was originally added as a hot spare.
Additional minor changes include fixing check_in_use() to use
a partition instead of a slice suffix. And is_spare() was moved
above make_disks() to avoid adding a forward reference.
