Hi all,

After merging the driver-core tree, today's linux-next build
(htmldocs) produced this warning:

Documentation/filesystems/api-summary:146: fs/debugfs/inode.c:804: WARNING: Inline literal start-string without end-string.

This is just a comment modification. Didn't see where my modification
caused this WARNING. :(

Yeah, I don't understand either, here's the diff, what's wrong with it?

Hi Greg and Qi,

The simple fix is to drop the percent (which is an inline code variant):

---- >8 ----
diff --git a/fs/debugfs/inode.c b/fs/debugfs/inode.c

LGTM, do I need to resend the patch with this fix?

Bagas needs to send it as a real fix so that I can apply it.

Got it. Thank you and Bagas very much.


thanks,
