           Summary: inode ref leaks with perf-test.sh

         Component: fuse
          Assignee: bugs at gluster.org

+++ This bug was initially created as a clone of Bug #1317948 +++

Description of problem:

While running perf-test.sh [1], I observed that the client memory usage was
quite high. A statedump revealed that there were inode leaks as deleted inodes
with nlookup=0 were present in the active list of the inode table.

xlator.mount.fuse.itable.active_size=600003
xlator.mount.fuse.itable.lru_size=1


Version-Release number of selected component (if applicable): mainline


How reproducible: Always


Steps to Reproduce:

1. touch files from a fuse mount point
2. list files using ls
3. delete files from the mount point
4. check memory usage and inode table usage
5. If there are no leaks, the inode table active size 

Actual results:

Memory and inode leaks are observed.


Expected results:

No memory and inode leaks should be found.
