From: Jerome Marchand Date: Wed, 28 Jul 2010 14:18:37 +0000 (-0400) Subject: inotify: Fix mask checks X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=44b350fc23e;p=linux-beck.git inotify: Fix mask checks The mask checks in inotify_update_existing_watch() and inotify_new_watch() are useless because inotify_arg_to_mask() sets FS_IN_IGNORED and FS_EVENT_ON_CHILD bits anyway.
