ec: Optimize read/write performance
This patch significantly improves performance of read/write
operations on a dispersed volume by reusing previous inodelk/
entrylk operations on the same inode/entry. This reduces the
latency of each individual operation considerably.
Inode version and size are also updated when needed instead
of on each request. This gives an additional boost.
This is a backport of http://review.gluster.org/8369/
