Documentation: ext4: correct the document about superblock

2022-09-27T19:21:42+00:00

The description of s_lastcheck_hi, s_first_error_time_hi, and s_last_error_time_hi fields refer to themselves, while these means referring to upper 8 bits (byte) of corresponding fields (s_lastcheck, s_first_error_time, and s_last_error_time). Correct the mistake. Signed-off-by: JunChao Sun Reviewed-by: Darrick J. Wong Link: https://lore.kernel.org/r/20220815125233.2040-1-sunjunchao2870@gmail.com Signed-off-by: Jonathan Corbet

Documentation: ext4: fix cell spacing of table heading on blockmap table

2022-08-03T03:56:02+00:00

Commit 3103084afcf234 ("ext4, doc: remove unnecessary escaping") removes redundant underscore escaping, however the cell spacing in heading row of blockmap table became not aligned anymore, hence triggers malformed table warning: Documentation/filesystems/ext4/blockmap.rst:3: WARNING: Malformed table. +---------------------+------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | i.i_block Offset | Where It Points | ... The warning caused the table not being loaded. Realign the heading row cell by adding missing space at the first cell to fix the warning.

According to document and code, ext4_xattr_header's size is 32 bytes, so h_reserved size should be 3. Signed-off-by: Wang Jianjian Link: https://lore.kernel.org/r/92fcc3a6-7d77-8c09-4126-377fcb4c46a5@huawei.com Signed-off-by: Theodore Ts'o Cc: stable@kernel.org

ext4: docs: Take out unneeded escaping

2021-10-07T14:46:02+00:00

The new file Documentation/orphan/ext4.rst escapes underscores ("\_") throughout. However, RST doesn't actually require that, so the escaping only succeeds in making the document less readable. Remove the unneeded escapes. Reviewed-by: Jan Kara Link: https://lore.kernel.org/r/20210902220854.198850-3-corbet@lwn.net Signed-off-by: Jonathan Corbet

ext4: docs: switch away from list-table

2021-10-07T14:46:02+00:00

Commit 3a6541e97c03 (Add documentation about the orphan file feature) added a new document on orphan files, which is great. But the use of "list-table" results in documents that are absolutely unreadable in their plain-text form. Switch this file to the regular RST table format instead; the rendered (HTML) output is identical.

ext4: update journal documentation

2021-06-23T01:34:17+00:00

Add a section about journal checkpointing, including information about the ioctl EXT4_IOC_CHECKPOINT which can be used to trigger a journal checkpoint from userspace. Also, update the journal allocation information to reflect that up to 10240000 blocks are used for the journal and that the journal is not necessarily contiguous.
