Re: Memory leak in GlusterFS FUSE client

[Soumya Koduri <skoduri@xxxxxxxxxx>]

I have made changes to fix the lookup leak in a different way (as 
discussed with Pranith) and uploaded them in the latest patch set #4
	- http://review.gluster.org/#/c/13096/

Please check if it resolves the mem leak and hopefully doesn't result in 
any assertion :)

Thanks,
Soumya
