If full-offload scan is used, the NIC driver (or rather the firmware of
the NIC) should take care of interrupting and continuing the background
scan. So net80211 should ignore the vap->iv_bgscanidle setting then, instead
the NIC driver might look at this setting and pass it on to the firmware
in some way if possible.
Since full-offload scans won't be explicitly interrupted by net80211, it
also doesn't really make sense to check the vap->iv_bgscanidle condition
in that case, before starting a background scan. If the NIC driver
advertises background scan support and full-offload scanning, the firmware
should be able to execute that scan without interfering too much with our
data traffic.

do any speculations about readahead, and use exactly the amount of readahead
specified by user. E.g. setting SF_FLAGS(0, SF_USER_READAHEAD) will guarantee
that no readahead at all will be performed.
sendfile_swapin() loop works this way:
- Find first invalid page in the request.
- Do vm_pager_has_page() and get count of pages, that can be taken in
single I/O.
- Trim valid pages from the end of the request.
- Cycle through the request and substitute to bogus_page all valid
pages that are in the middle of the request.
- After I/O launched (pager copies array of pages into buf(9), it
is important to restore proper page pointers with help vm_page_lookup().
Count bogus pages used and report them in sendfile stats.
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.

The salt based checksum mechanisms, such as skein, are storing the seed
in spa structure, and need to access the spa to use the seed. The current
mechanism for quick access to correct spa is via pointer provided by
vdev structure, but unfortunately the current code does set spa only
for the leaf vdev. This patch will fix the issue by making sure the
loader zfs reader will set spa also for top-level vdevs.

Some tools produce objects with a combined strtab and shstrtab.
These objects are not supported by crunchide since it rewrites the
symtab and strtab to "hide" symbols. This invalidates section header
offsets into a combined strtab/shstrtab.
In the future we could support these objects (by ensuring that we retain
unmodified section name strings in the output .strtab, and then rewriting
each section header's sh_name).
