The patch titled Subject: drm/msm: remove unlikely() from WARN_ON() conditions has been added to the -mm tree. Its filename is drm-msm-remove-unlikely-from-warn_on-conditions.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/drm-msm-remove-unlikely-from-warn_on-conditions.patch and later at http://ozlabs.org/~akpm/mmotm/broken-out/drm-msm-remove-unlikely-from-warn_on-conditions.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: Denis Efremov <efremov@xxxxxxxxx> Subject: drm/msm: remove unlikely() from WARN_ON() conditions "unlikely(WARN_ON(x))" is excessive. WARN_ON() already uses unlikely() internally.
