From: Eric Paris Date: Fri, 18 Dec 2009 02:24:22 +0000 (-0500) Subject: fsnotify: fsnotify_obtain_group should be fsnotify_alloc_group X-Git-Tag: v3.12-rc1~9229^2~103 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ffab83402f01555a5fa32efb48a4dd0ce8d12ef5;p=kernel%2Fkernel-generic.git fsnotify: fsnotify_obtain_group should be fsnotify_alloc_group fsnotify_obtain_group was intended to be able to find an already existing group. Nothing uses that functionality. This just renames it to fsnotify_alloc_group so it is clear what it is doing.
