When iterating over the input nvlist in dsl_props_set_sync_impl() when we don't
preserve the nvpair name before looking up ZPROP_VALUE, so when we later go to
process it nvpair_name() is always "value" and not the actual property name.
This fixes a couple of bugs in zfs_ioc_recv():
* Received properties were not restored correctly when failing to receive an

* Received properties were not completely replaced by the new ones when

zpool iostat allows you to specify only certain vdevs to display.
Currently, if you run 'zpool iostat -c CMD vdev1 vdev2 ...'
on specific vdevs, it will actually run the command on *all* vdevs,
and just display the results for the vdevs you specify. This patch
corrects the behavior to only run the command on the specified vdevs,
and also enables the zpool_iostat_005_pos.ksh tests.

This patch adds a command (-c) option to zpool status and zpool iostat. The
-c option allows you to run an arbitrary command on each vdev and display
the first line of output in zpool status/iostat. The environment vars
VDEV_PATH and VDEV_UPATH are set to the vdev's path and "underlying path"
before running the command. For device mapper, multipath, or partitioned
vdevs, VDEV_UPATH is the actual underlying /dev/sd* disk. This can be useful
if the command you're running requires a /dev/sd* device.
The patch also uses /sys/block/<dev>/slaves/ to lookup the underlying device
instead of using libdevmapper. This not only removes the libdevmapper
requirement at build time, but also allows you to resolve device mapper
devices without being root. This means that UDEV_UPATH get set correctly
when running zpool status/iostat as an unprivileged user.
Example:
$ zpool status -c 'echo I am $VDEV_PATH, $VDEV_UPATH'
NAME STATE READ WRITE CKSUM
mypool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
mpatha ONLINE 0 0 0 I am /dev/mapper/mpatha, /dev/sdc

ZFS Test Suite Performance Regression Tests
This was pulled into OpenZFS via the compressed arc featureand was
separated out in zfsonlinux as a separate pull request from PR-4768.
It originally came in as QA-4903 in Delphix-OS from John Kennedy.
Expected Usage:
$ DISKS="sdb sdc sdd" zfs-tests.sh -r perf-regression.run
Porting Notes:
1. Added assertions in the setup script to make sure required tools
(fio, mpstat, ...) are present.
2. For the config.json generation in perf.shlib used arcstats and
other binaries instead of dtrace to query the values.
3. For the perf data collection:
- use "zpool iostat -lpvyL" instead of the io.d dtrace script
(currently not collecting zfs_read/write latency stats)
- mpstat and iostat take different arguments
- prefetch_io.sh is a placeholder that uses arcstats instead of
dtrace
4. Build machines require fio, mdadm and sysstat pakage (YMMV).
Future Work:
- Need a way to measure zfs_read and zfs_write latencies per pool.
- Need tools to takes two sets of output and display/graph the
differences
- Bring over additional regression tests from Delphix
