quick-read: refactor
- peel out 'open behind' functionality into a separate translator - issue where, if file size had grown by revalidate, data was not flushed - removed unnecessary acquistion of table->lock (e.g in qr_lookup()) - keep inode ctx persistent, prune only data (effectively changing the order of lock acquisition from INODE -> TABLE) - validation with readdirplus - use variable size iobufs to simply cached reads Change-Id: If1586d0298fd1697ddff9fd7008efb3d286d436a BUG: 846240 Signed-off-by: Anand Avati <avati@redhat.com> Reviewed-on: http://review.gluster.org/4403 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>
