Xiubo Li 3cdce751b0 ceph: fix incorrect revoked caps assert in ceph_fill_file_size() ... commit 15c0a870dc44ed14e01efbdd319d232234ee639f upstream. When truncating the inode the MDS will acquire the xlock for the ifile Locker, which will revoke the 'Frwsxl' caps from the clients. But when the client just releases and flushes the 'Fw' caps to MDS, for exmaple, and once the MDS receives the caps flushing msg it just thought the revocation has finished. Then the MDS will continue truncating the inode and then issued the truncate notification to all the clients. While just before the clients receives the cap flushing ack they receive the truncation notification, the clients will detecte that the 'issued | dirty' is still holding the 'Fw' caps.
