Subject[PATCH 01/13] fs: Use a common define for inode slab caches
Date
From: Dave Chinner <dchinner@redhat.com>

All inode slab cache initialisation calls need to use specific flags
so that certain core functionality works correctly (e.g. reclaimable
memory accounting). Some of these flags are used inconsistently
across different filesystems, so inode cache slab behaviour can vary
according to filesystem type.

Wrap all the SLAB_* flags relevant to inode caches up into a single
SLAB_INODES flag and convert all the inode caches to use the new
flag.
