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. diff --git a/fs/xfs/linux-2.6/xfs_super.c b/fs/xfs/linux-2.6/xfs_super.c index 8c4f4476e5c..758df94690e 100644 --- a/fs/xfs/linux-2.6/xfs_super.c +++ b/fs/xfs/linux-2.6/xfs_super.c @@ -90,7 +90,6 @@ mempool_t *xfs_ioend_pool; #define MNTOPT_BARRIER "barrier" /* use writer barriers for log write and * unwritten extent conversion */ #define MNTOPT_NOBARRIER "nobarrier" /* .. disable */ -#define MNTOPT_OSYNCISOSYNC "osyncisosync" /* o_sync is REALLY o_sync */ #define MNTOPT_64BITINODE "inode64" /* inodes can be allocated anywhere */ #define MNTOPT_IKEEP "ikeep" /* do not free empty inode clusters */ #define MNTOPT_NOIKEEP "noikeep" /* free empty inode clusters */ @@ -274,8 +273,6 @@ xfs_parseargs( mp->m_flags &= ~XFS_MOUNT_GRPID; } else if (!strcmp(this_char, MNTOPT_WSYNC)) { mp->m_flags |= XFS_MOUNT_WSYNC; - } else if (!strcmp(this_char, MNTOPT_OSYNCISOSYNC)) { - mp->m_flags |= XFS_MOUNT_OSYNCISOSYNC; } else if (!strcmp(this_char, MNTOPT_NORECOVERY)) { mp->m_flags |= XFS_MOUNT_NORECOVERY; } else if (!strcmp(this_char, MNTOPT_NOALIGN)) { @@ -366,9 +363,11 @@ xfs_parseargs( cmn_err(CE_WARN, "XFS: ihashsize no longer used, option is deprecated."); } else if (!strcmp(this_char, "osyncisdsync")) { - /* no-op, this is now the default */ cmn_err(CE_WARN, - "XFS: osyncisdsync is now the default, option is deprecated."); + "XFS: osyncisdsync has no effect, option is deprecated."); + } else if (!strcmp(this_char, "osyncisosync")) { + cmn_err(CE_WARN, + "XFS: osyncisosync has no effect, option is deprecated."); } else if (!strcmp(this_char, "irixsgid")) { cmn_err(CE_WARN, "XFS: irixsgid is now a sysctl(2) variable, option is deprecated."); @@ -500,7 +499,6 @@ xfs_showargs( { XFS_MOUNT_SWALLOC, "," MNTOPT_SWALLOC }, { XFS_MOUNT_NOUUID, "," MNTOPT_NOUUID }, { XFS_MOUNT_NORECOVERY, "," MNTOPT_NORECOVERY }, - { XFS_MOUNT_OSYNCISOSYNC, "," MNTOPT_OSYNCISOSYNC }, { XFS_MOUNT_ATTR2, "," MNTOPT_ATTR2 }, { XFS_MOUNT_FILESTREAMS, "," MNTOPT_FILESTREAM }, { XFS_MOUNT_GRPID, "," MNTOPT_GRPID }, diff --git a/fs/xfs/xfs_mount.h b/fs/xfs/xfs_mount.h index e70dc39394a..622da2179a5 100644 --- a/fs/xfs/xfs_mount.h +++ b/fs/xfs/xfs_mount.h @@ -220,8 +220,6 @@ typedef struct xfs_mount { #define XFS_MOUNT_GRPID (1ULL << 9) /* group-ID assigned from directory */ #define XFS_MOUNT_NORECOVERY (1ULL << 10) /* no recovery - dirty fs */ #define XFS_MOUNT_DFLT_IOSIZE (1ULL << 12) /* set default i/o size */ -#define XFS_MOUNT_OSYNCISOSYNC (1ULL << 13) /* o_sync is REALLY o_sync */ - /* osyncisdsync is now default*/ #define XFS_MOUNT_32BITINODES (1ULL << 14) /* do not create inodes above * 32 bits in size */ #define XFS_MOUNT_SMALL_INUMS (1ULL << 15) /* users wants 32bit inodes */ |
