Its filename is maccess-remove-duplicate-kerneldoc-comments.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/maccess-remove-duplicate-kerneldoc-comments.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/maccess-remove-duplicate-kerneldoc-comments.patch Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Christoph Hellwig Subject: maccess: remove duplicate kerneldoc comments Many of the maccess routines have a copy of the kerneldoc comment in the header. Remove it as it is not useful and will get out of sync sooner or later.
