COMMIT: https://review.gluster.org/12271 committed in master by Raghavendra G (rgowdapp) ------ commit b9406e210717621bc672a63c1cbd1b0183834056 Author: Sakshi <sabansal> Date: Mon Jan 23 12:11:49 2017 +0530 cluster/dht: Make optimal usage of buffer provided with readdir(p) dht_readdirp must unwind with list of entries only after the entire buffer requested by kernel is filled to avoid extra syscalls occuring when returning partially filled buffer. Also wind readdir call to next subvol on reaching EOD for directory on that subvol to avoid extra network call.
