Subject: [PATCH v2] ntfs: fix incorrect kernel-doc comment syntax in files
Date:   Mon, 22 Mar 2021 22:41:31 +0530

Precedence: bulk

The opening comment mark '/**' is used for highlighting the beginning of
kernel-doc comments.
There are certain files in fs/ntfs which follow this syntax, but the
content inside does not comply with kernel-doc.
Such lines were probably not meant for kernel-doc parsing, but are parsed
due to the presence of kernel-doc like comment syntax(i.e, '/**'),
which causes unexpected warnings from kernel-doc.

E.g., presence of kernel-doc like comment in the header for
fs/ntfs/attrib.c, causes these unexpected warnings by kernel-doc:
"warning: Incorrect use of kernel-doc format:  * ntfs_map_runlist_nolock - map (a part of) a runlist of an ntfs inode"
"warning: Function parameter or member 'ni' not described in 'ntfs_map_runlist_nolock'"
"warning: Function parameter or member 'vcn' not described in 'ntfs_map_runlist_nolock'"
"warning: Function parameter or member 'ctx' not described in 'ntfs_map_runlist_nolock'"
"warning: expecting prototype for c(). Prototype was for ntfs_map_runlist_nolock() instead"

Similarly for other files too.

Provide a simple fix by replacing such occurrences with general comment
format, i.e. '/*', to prevent kernel-doc from parsing it.

Also fix enum documentation format at "ntfs_compression_constants", in
fs/ntfs/compress.c, by prefixing 'enum' keyword to the comment
description.

Changes in v2:
- prefix 'enum' keyword at "ntfs_compression_constants - enum of constants used in the compression code" comment in fs/ntfs/compress.c
- modify comment message correspondingly
