From b3b38d842fa367d862b83e7670af4e0fd6a80fc0 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Wed, 12 May 2010 15:34:07 -0700 Subject: inotify: don't leak user struct on inotify release inotify_new_group() receives a get_uid-ed user_struct and saves the reference on group->inotify_data.user. The problem is that free_uid() is never called on it. Issue seem to be introduced by 63c882a0 (inotify: reimplement inotify using fsnotify) after 2.6.30.
