929d0128f7 MFV r304159: 7277 zdb should be able to print zfs_dbgmsg's
illumos/illumos-gate@29bdd2f916
https://github.com/illumos/illumos-gate/commit/29bdd2f916366ece37c4748bca6b3d61f

https://www.illumos.org/issues/7277
  ztest always prints the debug messages (zfs_dbgmsg()) by calling
  zfs_dbgmsg_print(). We should add a flag to zdb to make it do this as well
  before exiting.

  The problem is that ztest_fault_inject() can inject multiple faults into the
  same block. It is designed such that it can inject errors on all leafs of a
  RAID-Z or mirror, but for a given range of offsets, it will only inject errors

efa0867fb0 MFV r302991: 6950 ARC should cache compressed data
illumos/illumos-gate@dcbf3bd6a1
dcbf3bd6a1

https://www.illumos.org/issues/6950
  When reading compressed data from disk, the ARC should keep the compressed
  block cached and only decompress it when consumers access the block. The
  uncompressed data should be short-lived allowing the ARC to cache a much larger
  amount of data. The DMU would also maintain a smaller cache of uncompressed
  blocks to minimize the impact of decompressing frequently accessed blocks.

  I got a patch from someone who uses nvpair code outside of illumos. It fixes a
  couple of gcc warnings/bugs for him.
     1. silence uninitialized use warnings
     2. add parentheses around assignment used as truth value
     3. fix printf format specifier (ll is for integers only)
     4. strstr, strspn, strcspn, and strcmp are declared in string.h, not
        strings.h.
     5. avoid scanning integer into boolean variable

  This affects, at least, zfs_mount_009_neg and zfs_mount_all_001_pos, both
  failing on that step. The pool containing the /export/home hierarchy is
  included in KEEP variable, but it doesn't seem to affect anything here.

https://github.com/illumos/illumos-gate/commit/4a20c933b148de8a1c1d3538391c64284
e636653

https://www.illumos.org/issues/6111
  If you create a zfs child folder, zfs send returns an error when a recursive
  incremental send is done between two snapshots made prior to the folder
  creation.
  The problem can be reproduced with the following steps.
  root@zfs:/# zfs create pool/test
  root@zfs:/# zfs snapshot pool/test@snap1
  root@zfs:/# zfs snapshot pool/test@snap2
  root@zfs:/# zfs create pool/test/child
  root@zfs:/# zfs send -R -I pool/test@snap1 pool/test@snap2 > /dev/null
  WARNING: could not send pool/test/child@snap2: does not exist
  WARNING: could not send pool/test/child@snap2: does not exist
  root@zfs:/# echo $?
  1
  root@zfs:/# zfs snapshot -r pool/test@snap3
  root@zfs:/# zfs send -R -I pool/test@snap1 pool/test@snap3 > /dev/null
  root@zfs:/# echo $?
  0
  root@zfs:/# zfs send -R -I pool/test@snap2 pool/test@snap3 > /dev/null
  root@zfs:/# echo $?
  0
  Since pool/test/child was created after snap2, zfs send should not expect snap2
  to be in pool/test/child when doing a recursive send. It should examine the
  compare the creation time of the snapshot and each child folder to decide if
  the folder will be sent. The next incremental send between snap2 and snap3
  would properly create the child folder and snap3 which first appears in the
  child folder.
  The problem is identical if '-i' is used instead of '-I'.

723af0425e fix bug introduced in r297521, set canmount=on doesn't mount filesystem
There are two cases where changing canmount should result in an action:
- canmount is set to off for a mounted filesystem
- canmount is set to on for an unmounted filesystem
Before r297521 we could unmount and re-mount a filesystem when that was
not necessary, but after r297521 we only handled the first of the above
cases.

7085 add support for "if" and "else" statements in dtrace

illumos/illumos-gate@c3bd3abd88

Add syntactic sugar to dtrace: "if" and "else" statements. The sugar is
baked down to standard dtrace features by adding additional clauses with
the appropriate predicates.

Some of the testcases fail, but this at least bypasses the panic behavior

495ec94fd7 MFV r303082: 6391 Override default SPA config location via environment
illumos/illumos-gate@ae24175b2b
ae24175b2b

https://www.illumos.org/issues/6391
  When using zdb with non-default SPA config file it is not convenient
  to add -U <non-default-config-file-path> all the time. This commit
  introduces support for setting/overriding SPA config location via
  environment variable 'SPA_CONFIG_PATH'.
  If -U flag is specified in the command line it will override any other
  value as usual.

15dbc1605b On FreeBSD there is a setsockopt option SO_USER_COOKIE which allows
setting a 32 bit value on each socket. This can be used by applications
and DTrace as a rendezvous point so that an applicaton's data can
more easily be captured at run time. Expose the user cookie via
DTrace by updating the translator in tcp.d and add a quick test
program, a TCP server, that sets the cookie on each connection
accepted.

7a0c41d5d7 zfsd(8), the ZFS fault management daemon
Add zfsd, which deals with hard drive faults in ZFS pools. It manages
hotspares and replements in drive slots that publish physical paths.

cddl/usr.sbin/zfsd
	Add zfsd(8) and its unit tests

lib/libdevdctl

lib/Makefile
share/mk/bsd.libnames.mk
share/mk/src.libnames.mk
	Add libdevdctl to the build. It's a private library, unusable by
	out-of-tree software.

	By default, set zfsd_enable to NO

etc/mtree/BSD.include.dist
	Add a directory for libdevdctl's include files

etc/mtree/BSD.tests.dist
	Add a directory for zfsd's unit tests

etc/mtree/BSD.var.dist
	Add /var/db/zfsd/cases, where zfsd stores case files while it's shut
	down.

etc/rc.d/Makefile
etc/rc.d/zfsd
	Add zfsd's rc script

sys/cddl/contrib/opensolaris/uts/common/fs/zfs/vdev.c
	Fix the resource.fs.zfs.statechange message. It had a number of
	problems:

	It was only being emitted on a transition to the HEALTHY state.
	That made it impossible for zfsd to take actions based on drives
	getting sicker.

	It compared the new state to vdev_prevstate, which is the state that
	the vdev had the last time it was opened.  That doesn't make sense,
	because a vdev can change state multiple times without being
	reopened.

	vdev_set_state contains logic that will change the device's new
	state based on various conditions.  However, the statechange event
	was being posted _before_ that logic took effect.  Now it's being
	posted after.
