@ -131,17 +131,6 @@ When mounting an XFS filesystem, the following options are accepted.
Don't check for double mounted file systems using the file system uuid.
This is useful to mount LVM snapshot volumes.
osyncisosync
Make O_SYNC writes implement true O_SYNC. WITHOUT this option,
Linux XFS behaves as if an "osyncisdsync" option is used,
which will make writes to files opened with the O_SYNC flag set
behave as if the O_DSYNC flag had been used instead.
This can result in better performance without compromising
data safety.
However if this option is not in effect, timestamp updates from
O_SYNC writes can be lost if the system crashes.
If timestamp updates are critical, use the osyncisosync option.
uquota/usrquota/uqnoenforce/quota
User disk quota accounting enabled, and limits (optionally)
enforced. Refer to xfs_quota(8) for further details.
