20# DESCRIPTION:
21#	Concurrent sync writes with log offline/online works.
22#
23# STRATEGY:
24#	1. Configure "zfs_commit_timeout_pct"
25#	2. Create pool with a log device.
26#	3. Concurrently do the following:
27#	   3.1. Perform 8K sync writes
28#	   3.2. Perform log offline/online commands
29#	4. Loop to test with growing "zfs_commit_timout_pct" values.
