Tony Nguyen ef57371a92 Do not enable stack tracer for ZFS performance test
Linux ZFS test suite runs with /proc/sys/kernel/stack_tracer_enabled=1,
via zfs.sh script, which has negative performance impact, up to 40%.

Since large stack is a rare issue now, preferred behavior would be:
- making stack tracer an opt-in feature for zfs.sh
- zfs-test.sh enables stack tracer only when requested

-h Show this message
-v Verbose zfs-tests.sh output
-q Quiet test-runner output
-x Remove all testpools, dm, lo, and files (unsafe)
-k Disable cleanup after test failure
-f Use files only, disables block device tests
-S Enable stack tracer (negative performance impact)
-c Only create and populate constrained path
-I NUM Number of iterations
-d DIR Use DIR for files and loopback devices
-s SIZE Use vdevs of SIZE (default: 4G)
-r RUNFILE Run tests in RUNFILE (default: linux.run)
-t PATH Run single test at PATH relative to test suite
-T TAGS Comma separated list of tags (default: 'functional')
-u USER Run single test as USER (default: root)
EXAMPLES:
# Run the default (linux) suite of tests and output the configuration used.
$0 -v
# Run a smaller suite of tests designed to run more quickly.
$0 -r linux-fast
# Cleanup a previous run of the test suite prior to testing, run the
# default (linux) suite of tests and perform no cleanup on exit.
