Description Ram Raja 2018-06-25 10:11:30 UTC
Description of problem:

It's a correctness related issue that was reported by a developer

"inode's dirstat gets updated by request reply, but not by cap message. this is problematic.

For example:
...
MDS modifies a directory
MDS issues CEPH_STAT_CAP_INODE_ALL to client
...

user stat(2) the directory
cephfs client finds that it has all shared caps locally, it return dirstat.size() as directory size."
