Return to 121 CVS log

Up to [Development] / xfs-cmds / xfstests

test 121 creates unlinked and still referenced inodes, it doesn't clean up afterwards.
Merge of master-melb:xfs-cmds:28637a by kenmcd.

  do a mount after running test to trigger log recovery
  \.

#! /bin/sh
# FS QA Test No. 121
#
# To test log replay for the unlinked list.
# So we create unlinked and still referenced inodes
# and make sure that no clearing of the unlinked AGI buckets
# are happening.
# See pv#953263.
