To avoid having many tests repeating the following pattern:
_load_flakey_table $FLAKEY_DROP_WRITES
_unmount_flakey
_load_flakey_table $FLAKEY_ALLOW_WRITES
_mount_flakey
add the helper function _flakey_drop_and_remount to remove
the existing duplicated code and serve as a shortcut.

# FSQA Test No. 107
|
|
#
|
|
# Test that when we have a file with multiple hard links belonging to different
|
|
# parent directories, if we remove one of those links, fsync the file using one
|
|
# of its other links (that has a parent directory different from the one we
|
|
# removed a link from), power fail and then replay the fsync log/journal, the
|
|
# hard link we removed is not available anymore and all the filesystem metadata
|
|
# is in a consistent state.
