226	# So to get tags for our selected tests we do:
227	#
228	# 1. Remove unneeded chars: [],\
229	# 2. Print out the last field of each tag line.  This will be the tag
230	#    for the test (like 'zpool_add').

232	#    in multiple runfiles, then when you do '-T <tag>' ZTS is smart
233	#    enough to know to run the tag in each runfile.  So '-T zpool_add'
234	#    will run the zpool_add from common.run and linux.run.
235	# 4. Ignore the 'functional' tag since we only want individual tests
236	# 5. Print out the tests in our faction of all tests.  This uses modulus
237	#    so "1/3" will run tests 1,3,6,9 etc.  That way the tests are
238	#    interleaved so, say, "3/4" isn't running all the zpool_* tests that

360	-q          Quiet test-runner output
361	-D          Debug; show all test output immediately (noisy)
362	-x          Remove all testpools, dm, lo, and files (unsafe)
363	-k          Disable cleanup after test failure
364	-K          Log test names to /dev/kmsg
365	-f          Use files only, disables block device tests
366	-S          Enable stack tracer (negative performance impact)
367	-c          Only create and populate constrained path
368	-R          Automatically rerun failing tests
369	-m          Enable kmemleak reporting (Linux only)
370	-n NFSFILE  Use the nfsfile to determine the NFS configuration
371	-I NUM      Number of iterations
372	-d DIR      Use world-writable DIR for files and loopback devices
373	-s SIZE     Use vdevs of SIZE (default: 4G)

377	-T TAGS     Comma separated list of tags (default: 'functional')
378	            Alternately, specify a fraction like "1/3" or "2/3" to

380		     is useful for splitting up the test amongst different
381		     runners.
382	-u USER     Run single test as USER (default: root)
383
