Deprecated Mount Options
========================
delaylog/nodelaylog
Delayed logging is the only logging method that XFS supports
now, so these mount options are now ignored.
Due for removal in 3.12.
ihashsize=value
In memory inode hashes have been removed, so this option has
no function as of August 2007. Option is deprecated.
Due for removal in 3.12.
None at present.
irixsgid
This behaviour is now controlled by a sysctl, so the mount
option is ignored.
Due for removal in 3.12.
Removed Mount Options
=====================
osyncisdsync
osyncisosync
O_SYNC and O_DSYNC are fully supported, so there is no need
for these options any more.
Name Removed
---- -------
delaylog/nodelaylog v3.20
ihashsize v3.20
irixsgid v3.20
osyncisdsync/osyncisosync v3.20
Due for removal in 3.12.
