31 When mounting the filesystem, use the "-o dax" option on the command line or
32 add 'dax' to the options in /etc/fstab. This works to enable DAX on all files
33 within the filesystem. It is equivalent to the '-o dax=always' behavior below.
56 4. There exist dax mount options which can override FS_XFLAG_DAX in the
60 "-o dax=inode" means "follow FS_XFLAG_DAX" and is the default.
62 "-o dax=never" means "never set S_DAX, ignore FS_XFLAG_DAX."
64 "-o dax=always" means "always set S_DAX ignore FS_XFLAG_DAX."
66 "-o dax" is a legacy option which is an alias for "dax=always".
67 This may be removed in the future so "-o dax=always" is
71 the same even when the filesystem is mounted with a dax option. However,
73 remounted with dax=inode and the inode is evicted from kernel memory.
