5a453d5f5b libcapsicum: Introduce caph_{rights,ioctls,fcntls}_limit
The idea behind those functions is not to force consumers to remember that there
is a need to check errno on failure. We already have a caph_enter(3) function
which does the same for cap_enter(2).

10f42d244b Convert epoch to read / write records per cpu
In discussing D17503 "Run epoch calls sooner and more reliably" with
sbahra@ we came to the conclusion that epoch is currently misusing the
ck_epoch API. It isn't safe to do a "write side" operation (ck_epoch_call
or ck_epoch_poll) in the middle of a "read side" section. Since, by definition,
it's possible to be preempted during the middle of an EPOCH_PREEMPT
epoch the GC task might call ck_epoch_poll or another thread might call
ck_epoch_call on the same section. The right solution is ultimately to change
the way that ck_epoch works for this use case. However, as a stopgap for
12 we agreed to simply have separate records for each use case.

b4d66a1739 9952 Block size change during zfs receive drops spill block
Replication code in receive_object() falsely assumes that if received
object block size is different from local, then it must be a new object
and calls dmu_object_reclaim() to wipe it out. In most cases it is not a
problem, since all dnode, bonus buffer and data block(s) are immediately
rewritten any way, but the problem is that spill block (if used) is not.
This means loss of ACLs, extended attributes, etc.

This issue can be triggered in very simple way:
1. create 4KB file with 10+ ACL entries;
2. take snapshot and send it to different dataset;
3. append another 4KB to the file;
4. take another snapshot and send incrementally;
5. witness ACL loss on receive side.

4db78cacde Remove apparently unused 0-byte files that cause grief on Windows
r235274 added a sort regression test (it operates by comparing output
against GNU sort).  The commit included a number of 0-byte files, one
of which ends in a trailing . which reportedly breaks svn/git checkouts
on Windows.

It appears these were added accidentally, so just remove them.

4668666fe4 Implement ability to turn on/off PHYs for AHCI devices.
As part of Chuck's work on fixing kernel crashes caused by disk I/O
errors, it is useful to be able to trigger various kinds of
errors. This patch allows causing an AHCI-attached disk to disappear,
by having the driver keep the PHY disabled when the driver would
otherwise enable the PHY. It also allows making the disk reappear by
having the driver go back to setting the PHY enable/disable state as
it normal would and simulating the hardware event that causes a bus
rescan.
