  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_timeout_pct" values.

  39         # enter this function without previously waiting for them.
