40 - Create a new filesystem using the ext4 filesystem type:
42 # mke2fs -t ext4 /dev/hda1
53 (Note: we currently do not have tools to convert an ext4
59 # mount -t ext4 /dev/hda1 /wherever
65 note that ext4 enables write barriers by default, while ext3 does
68 '-o barriers=[0|1]' mount option for both ext3 and ext4 filesystems

128 When mounting an ext4 filesystem, the following option are accepted:
131 ro Mount filesystem read only. Note that ext4 will
197 consistency with other ext4 mount options.
200 number of inode table blocks that ext4's inode
266 delalloc (*) Defer block allocation until just before ext4
268 allows ext4 to better allocation decisions
276 max_batch_time=usec Maximum amount of time ext4 should wait for

317 If auto_da_alloc is enabled, ext4 will detect
344 discard Controls whether ext4 should issue discard/TRIM
363 dioread_lock Controls whether or not ext4 should use the DIO read
365 ext4 will allocate uninitialized extent before buffer

405 In data=ordered mode, ext4 only officially journals metadata, but it logically
423 Information about mounted ext4 file systems can be found in
424 /proc/fs/ext4. Each mounted filesystem will have a directory in
425 /proc/fs/ext4 based on its device name (i.e., /proc/fs/ext4/hdc or
426 /proc/fs/ext4/dm-0). The files in each per-device directory are shown
429 Files in /proc/fs/ext4/<devname>
438 Information about mounted ext4 file systems can be found in
439 /sys/fs/ext4. Each mounted filesystem will have a directory in
440 /sys/fs/ext4 based on its device name (i.e., /sys/fs/ext4/hdc or
