Message-Id: <1464767580-22732-4-git-send-email-kernel@kyup.com>
Date: Wed, 1 Jun 2016 10:52:59 +0300
From: Nikolay Borisov <kernel@...p.com>
To: john@...nmccutchan.com, eparis@...hat.com, ebiederm@...ssion.com

Subject: [PATCH 3/4] misc: Rename the HASH_SIZE macro
This change is required since the inotify-per-namespace code added
hashtable.h to the include list of sched.h. This in turn causes
compiler warnings since HASH_SIZE is being defined in multiple
locations
