Subject: [PATCH 3/4] misc: Rename the HASH_SIZE macro

From: Nikolay Borisov <[email-masked]>
Date: Wed, 1 Jun 2016 10:52:59 +0300

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
