Val,
I'm just updating the mount(2) man page for MS_RELATIME, and this is the
text I've come up with:
MS_RELATIME(Since Linux 2.6.20)
When a file on this file system is accessed, only
update the file's last accessed time (atime) if
the current value of atime is less than or equal
to the file's last modified (mtime) or last sta-
tus change time (ctime). This option is useful
for programs, such as mutt(1), that need to know
when a file has been read since it was last modi-
fied.
This text is based on your comments accompanying the various patches, but
it differs in a respect. Your comments said that the atime would only be
updated if the atime is older than mtime/ctime. However, what the code
actually does is update atime if it is is <= mtime/ctime -- i.e., atime is
older than or *or equal to* mtime/ctime.
I'm sure that the code implements your intention, but before incorporating
the above text I thought I just better check, since the code differs from
your comment. Can you just confirm that the proposed man page text is okay.
Cheers,
Michael
