[Gluster-users] Memory leak in GlusterFS FUSE client

[Soumya Koduri]

I could reproduce while testing deep directories with in the mount 
point. I root caus'ed the issue & had discussion with Pranith to 
understand the purpose and recommended way of taking nlookup on inodes.

I shall make changes to my existing fix and post the patch soon.
Thanks for your patience!
