Description Yan, Zheng 2018-06-20 06:49:00 UTC
Description of problem:

readdir may get stale result after ceph-fuse's session become stale

How reproducible:

Steps to Reproduce:
1. create ceph-fuse mounts, create an empty directory, 'ls' the empty directory from both mount points. 
2. send signal STOP to one ceph-fuse, wait until its session stable become stale
3. create a file in the directory from mount point of another ceph-fuse 
4. send signal CONT to the stopped ceph-fuse, 'ls' the directory from from mount point of the resumed ceph-fuse.

Actual results:
'ls' result does not contain the new file 

Expected results:
'ls' result contains the new file
