Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

From: Dave Chinner <dchinner@xxxxxxxxxx>

The inode slab creation functions in different filesystem don't all set up the
slab caches correctly. Add a new flag SLAB_INODES that sets all the necessary
flags for an inode slab cache and convert all the callers to use it. THis makes
it easy to change the behaviour of all the inode slab caches in one go.
