md-cache: meta-data caching translator
This is a metadata caching translator which is well integrated with glusterfs core framework and leverages some of the recent protocol changes to do a better job at caching. - It uses the attributes returned along callbacks of all calls to update its attribute cache as frequently as possible without issuing calls on its own (i.e, very low overhead) - It caches attributes returned via readdirp into the inode contexts corresponding to those entries (i.e, well integrated) - It caches and updates xattrs and not just inode attributes (i.e, eliminates the need for a separate xattr-prefetch translator) In its current form it has a timeout based consistency model Change-Id: I891f6225c1a4c08bb111e287571d5f6d326dbe97 BUG: 765785 Reviewed-on: http://review.gluster.com/2713 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
