docs: ext4: modify the group desc size to 64

2023-03-08T01:24:05+00:00

Since the default ext4 group desc size is 64 now (assuming that the
64-bit feature is enbled). And the size mentioned in this doc is 64 too.
Change it to 64.

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.

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.

ext4, doc: fix incorrect h_reserved size

2022-04-13T02:24:46+00:00

According to document and code, ext4_xattr_header's size is 32 bytes, so
h_reserved size should be 3.

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.

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.
