[PATCH 1/2] dir: update stale description of treat_directory()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Derrick Stolee <stolee@xxxxxxxxx>

The documentation comment for treat_directory() was originally written
in 095952 (Teach directory traversal about subprojects, 2007-04-11)
which was before the 'struct dir_struct' split its bitfield of named
options into a 'flags' enum in 7c4c97c0 (Turn the flags in struct
dir_struct into a single variable, 2009-02-16). When those flags
changed, the comment became stale, since members like
'show_other_directories' transitioned into flags like
DIR_SHOW_OTHER_DIRECTORIES.

Update the comments for treat_directory() to use these flag names rather
than the old member names.
