nilfs2: revise the return value description style for consistency.

2025-01-25T06:47:25+00:00

Also for comments that do not cause kernel-doc warnings (those that list multiple error codes), revise the return value description style to match Brian G.'s suggestion of "..., or one of the following negative error codes on failure:".

nilfs2: add missing return value kernel-doc descriptions

2025-01-25T06:47:25+00:00

There are a number of kernel-doc comments for functions that are missing return values, which also causes a number of warnings when the kernel-doc script is run with the "-Wall" option. Fix this issue by adding proper return value descriptions, and improve code maintainability.

nilfs2: correct return value kernel-doc descriptions for metadata files

2025-01-25T06:47:25+00:00

Similar to the previous changes to fix return value descriptions, this fixes the format of the return value descriptions for metadata file functions other than sufile.

nilfs2: convert checkpoint file to be folio-based

2024-11-06T01:12:39+00:00

Regarding the cpfile, a metadata file that manages checkpoints, convert the page-based implementation to a folio-based implementation. This change involves some helper functions to calculate byte offsets on folios and removing a few helper functions that are no longer needed.

nilfs2: convert common metadata file code to be folio-based

2024-11-06T01:12:37+00:00

In the common routines for metadata files, nilfs_mdt_insert_new_block(), which inserts a new block buffer into the cache, is still page-based, and there are two places where bh_offset() is used. Convert these to page-based. Link: https://lkml.kernel.org/r/20241024092602.13395-3-konishi.ryusuke@gmail.com Signed-off-by: Ryusuke Konishi Cc: Matthew Wilcox (Oracle) Signed-off-by: Andrew Morton

nilfs2: treat missing cpfile header block as metadata corruption

2024-09-02T03:43:39+00:00

The cpfile, a metadata file that holds metadata for checkpoint management, also has statistical information in its first block, and if reading this block fails, it receives the internal code -ENOENT and returns that code to the callers. As with sufile, to prevent this -ENOENT from being propagated to system calls, return -EIO instead when reading the header block fails.

nilfs2: fix missing initial short descriptions of kernel-doc comments

2024-09-02T03:43:37+00:00

Update some kernel-doc comments that are missing the initial short description and fix the following warnings output by the kernel-doc script: fs/nilfs2/bmap.c:353: warning: missing initial short description on line: * nilfs_bmap_lookup_dirty_buffers - fs/nilfs2/cpfile.c:708: warning: missing initial short description on line: * nilfs_cpfile_delete_checkpoint - fs/nilfs2/cpfile.c:972: warning: missing initial short description on line: * nilfs_cpfile_is_snapshot - fs/nilfs2/dat.c:275: warning: missing initial short description on line: * nilfs_dat_mark_dirty - fs/nilfs2/sufile.c:844: warning: missing initial short description on line: * nilfs_sufile_get_suinfo - Link: https://lkml.kernel.org/r/20240816074319.3253-9-konishi.ryusuke@gmail.com Signed-off-by: Ryusuke Konishi Signed-off-by: Andrew Morton

nilfs2: use div64_ul() instead of do_div()

2024-03-12T20:09:23+00:00

Fixes Coccinelle/coccicheck warnings reported by do_div.cocci. Compared to do_div(), div64_ul() does not implicitly cast the divisor and does not unnecessarily calculate the remainder.
