The send size estimate for a zvol can be too low, if the size of the
record headers (dmu_replay_record_t's) is a significant portion of the
size. This is typically the case when the data is highly compressible,
especially with embedded blocks.
The problem is that dmu_adjust_send_estimate_for_indirects() assumes
that blocks are the size of the "recordsize" property (128KB). However,
for zvols, the blocks are the size of the "volblocksize" property (8KB).
Therefore, we estimate that there will be 16x less record headers than
there really will be.
The fix is to check the type of the object set (whether it is a zvol or
not) and pick the appropriate property. In addition, while we are at it,
we also add the size of the BEGIN and END records to the estimate.

dbuf_evict_notify() holds the dbuf_evict_lock while checking if it should
do the eviction itself (because the evict thread is not able to keep up).
This can result in massive lock contention. It isn't necessary to hold
the lock, because if we make the wrong choice occasionally, nothing bad
will happen. This commit results in a ~60% performance improvement for
ARC-cached sequential reads.

dmu_object_alloc() is single-threaded, so when multiple threads are
creating files in a single filesystem, they spend a lot of time waiting
for the os_obj_lock. To improve performance of multi-threaded file
creation, we must make dmu_object_alloc() typically not grab any
filesystem-wide locks.
The solution is to have a "next object to allocate" for each CPU. Each
of these "next object"s is in a different block of the dnode object, so
that concurrent allocation holds dnodes in different dbufs. When a
thread's "next object" reaches the end of a chunk of objects (by default
4 blocks worth -- 128 dnodes), it will be reset to the per-objset
os_obj_next, which will be increased by a chunk of objects (128). Only
when manipulating the os_obj_next will we need to grab the os_obj_lock.
This decreases lock contention dramatically, because each thread only
needs to grab the os_obj_lock briefly, once per 128 allocations.
This results in a 70% performance improvement to multi-threaded object
creation (where each thread is creating objects in its own directory),
from 67,000/sec to 115,000/sec, with 8 CPUs.

- After some ZIL changes 6 years ago zil_slog_limit got partially broken
due to zl_itx_list_sz not updated when async itx'es upgraded to sync.
Actually because of other changes about that time zl_itx_list_sz is not
really required to implement the functionality, so this patch removes
some unneeded broken code and variables.
- Original idea of zil_slog_limit was to reduce chance of SLOG abuse by
single heavy logger, that increased latency for other (more latency critical)
loggers, by pushing heavy log out into the main pool instead of SLOG. Beside
huge latency increase for heavy writers, this implementation caused double
write of all data, since the log records were explicitly prepared for SLOG.
Since we now have I/O scheduler, I've found it can be much more efficient
to reduce priority of heavy logger SLOG writes from ZIO_PRIORITY_SYNC_WRITE
to ZIO_PRIORITY_ASYNC_WRITE, while still leave them on SLOG.
- Existing ZIL implementation had problem with space efficiency when it
has to write large chunks of data into log blocks of limited size. In some
cases efficiency stopped to almost as low as 50%. In case of ZIL stored on
spinning rust, that also reduced log write speed in half, since head had to
uselessly fly over allocated but not written areas. This change improves
the situation by offloading problematic operations from z*_log_write() to
zil_lwb_commit(), which knows real situation of log blocks allocation and
can split large requests into pieces much more efficiently. Also as side
effect it removes one of two data copy operations done by ZIL code WR_COPIED
case.
- While there, untangle and unify code of z*_log_write() functions.
Also zfs_log_write() alike to zvol_log_write() can now handle writes crossing
block boundary, that may also improve efficiency if ZPL is made to do that.

When writing pre-compressed buffers, arc_write() requires that
the compression algorithm used to compress the buffer matches
the compression algorithm requested by the zio_prop_t, which is
set by dmu_write_policy(). This makes dmu_write_policy() and its
callers a bit more complicated.
We simplify this by making arc_write() trust the caller to supply
the type of pre-compressed buffer that it wants to write,
and override the compression setting in the zio_prop_t.

Commit torvalds/linux@9e8925b6 allowed for kernels to be built
without support for mandatory locking (MS_MANDLOCK). This will
result in 'zfs mount' failing when the nbmand=on property is set
if the kernel is built without CONFIG_MANDATORY_FILE_LOCKING.
Unfortunately we can not reliably detect prior to the mount(2) system
call if the kernel was built with this support. The best we can do
is check if the mount failed with EPERM and if we passed 'mand'
as a mount option and then print a more useful error message. e.g.
filesystem 'tank/fs' has the 'nbmand=on' property set, this mount
option may be disabled in your kernel. Use 'zfs set nbmand=off'
to disable this option and try to mount the filesystem again.
Additionally, switch the default error message case to use
strerror() to produce a more human readable message.

* slog_013_pos.ksh - Updated to use losetup under Linux.
* slog_014_pos.ksh - ZED will not be running, manually degrade
the damaged vdev as expected.
* nopwrite_varying_compression, nopwrite_volume - Forced pool
sync with sync_pool to ensure up to date property values.
* Fixed typos in ZED log messages. Refactored zed_* helper
functions to resolve all-syslog exit=1 errors in zedlog.

zpool_destroy_001_pos, largest_pool_001_pos, clone_001_pos.ksh,
clone_001_pos, - Skip until layering pools on zvols is solid.
* largest_pool_001_pos - Limited to 7eb pool, maximum
supported size in 8eb-1 on Linux.
* zpool_expand_001_pos, zpool_expand_003_neg - Requires
additional support from the ZED, updated skip reason.
* zfs_rollback_001_pos, zfs_rollback_002_pos - Properly cleanup
busy mount points under Linux between test loops.

This addition will enable us to sync an open TXG to the main pool
on demand. The functionality is similar to 'sync(2)' but 'zpool sync'
will return when data has hit the main storage instead of potentially
just the ZIL as is the case with the 'sync(2)' cmd.
