Set5 of 5 patchsets to update scsi, libsas, and libata in
support of the isci driver.
Commit 43a8d39d "[SCSI] fix async probe regression" found that
async_synchronize_full() was missing async work that was scheduled to
its own domain. This led James to note:
"My theory is that this is an init problem: The assumption in a lot of
our code is that async_synchronize_full() waits for everything ... even
the domain specific async schedules, which isn't true."
...and this set aims to make that assumption true, but also with the
ability to opt-out for "private" async work.
The other async probe fix is in the area of unplug events that occur in
the scsi async scanning interval. Essentially scsi_remove_target() can
now see semi-initialized scsi_targets that have yet to be added via
device_add().
If there are no objections I'll put these in -next. But I expect at
least patch1 and patch2 will need an ack from Arjan before the set shows
up in scsi.git.
