[Gluster-devel] GlusterFS v3.7.8 client leaks summary — part II

[Oleksandr Natalenko]

And here goes "rsync" test results (v3.7.8 + two patches by Soumya).

2 volumes involved: source and target.

=== Common indicators ===

slabtop before drop_caches: [1]
slabtop after drop_caches: [2]

=== Source volume (less interesting part) ===

RAM usage before drop_caches: [3]
statedump before drop_caches: [4]
RAM usage after drop_caches: [5]
statedump after drop_caches: [6]

=== Target volume (most interesting part) ===

RAM usage before drop_caches: [7]
statedump before drop_caches: [8]
RAM usage after drop_caches: [9]
statedump after drop_caches: [10]
Valgrind output: [11]

=== Conclusion ===

Again, see no obvious leaks.
