Return to 065 CVS log

Up to [Development] / xfs-cmds / xfstests

xfstests updates - rework build to be like other xfs packages, revive some old fs test tools and reenable xfs extensions, move ltp code into a separate subdir to help keeping in sync with real ltp project (hopefully)

#! /bin/sh
# XFS QA Test No. 065
#
# Testing incremental dumps and cumulative restores with
# "adding, deleting, renaming, linking, and unlinking files and 
#  directories".
# Do different operations for each level.
