linux-next: build failure after merge of the fsnotify tree

[Stephen Rothwell]

Hi Eric,

After merging the fsnotify tree, today's linux-next build
(powerpc_ppc64_defconfig) failed like this:

fs/notify/fdinfo.c: In function 'show_fdinfo':
fs/notify/fdinfo.c:30:18: error: 'struct fsnotify_group' has no member named 'mark_lock'
fs/notify/fdinfo.c:36:20: error: 'struct fsnotify_group' has no member named 'mark_lock'

Caused by commit 986ab09807ca ("fsnotify: use a mutex instead of a
spinlock to protect a groups mark list") interacting with commit
be77196b809c ("fs, notify: add procfs fdinfo helper") from Linus' tree
(via Andrew' tree).

I added the following merge fix patch:

From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Date: Wed, 19 Dec 2012 11:53:20 +1100
Subject: [PATCH] fsnotify: cope with change from spinlock to mutex
