Porting Notes:
- Utilities which aren't available under Linux have been removed.
- Because of sudo's default secure path behavior PATH must be
explicitly reset at the top of libtest.shlib. This avoids the
need for all users to customize secure path on their system.
- Updated ZoL infrastructure to manage constrained path
- Updated all test cases
- Check permissions for usergroup tests
- When testing in-tree create links under bin/
- Update fault cleanup such that missing files during
cleanup aren't fatal.
- Configure su environment with constrained path

Each test in the performance regression test suite
creates a pool and a dataset for use. Unfortunately,
these tests do not cleanup the pool and dataset
correctly once they complete. Each test now kills
fio and iostat, destroys the dataset, and finally
destroys the pool. Each test also now traps the
SIGTERM signal to handle cases where test-runner
kills a test.

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
