2014-10-14ceph: include the initial ACL in create/mkdir/mknod MDS requestsYan, Zheng1-6/+21
Current code set new file/directory's initial ACL in a non-atomic manner. Client first sends request to MDS to create new file/directory, then set the initial ACL after the new file/directory is successfully created. The fix is include the initial ACL in create/mkdir/mknod MDS requests. So MDS can handle creating file/directory and setting the initial ACL in one request.

2014-10-14ceph: request xattrs if xattr_version is zeroYan, Zheng1-3/+2
Following sequence of events can happen. - Client releases an inode, queues cap release message. - A 'lookup' reply brings the same inode back, but the reply doesn't contain xattrs because MDS didn't receive the cap release message and thought client already has up-to-data xattrs. The fix is force sending a getattr request to MDS if xattrs_version is 0. The getattr mask is set to CEPH_STAT_CAP_XATTR, so MDS knows client does not have xattr.

2013-08-15ceph: introduce i_truncate_mutexYan, Zheng1-1/+7
I encountered below deadlock when running fsstress wmtruncate work truncate MDS --------------- ------------------ -------------------------- lock i_mutex <- truncate file lock i_mutex (blocked) <- revoking Fcb (filelock to MIX) send request -> handle request (xlock filelock) At the initial time, there are some dirty pages in the page cache. When the kclient receives the truncate message, it reduces inode size and creates some 'out of i_size' dirty pages. wmtruncate work can't truncate these dirty pages because it's blocked by the i_mutex. Later when the kclient receives the cap message that revokes Fcb caps, It can't flush all dirty pages because writepages() only flushes dirty pages within the inode size. When the MDS handles the 'truncate' request from kclient, it waits for the filelock to become stable. But the filelock is stuck in unstable state because it can't finish revoking kclient's Fcb caps. The truncate pagecache locking has already caused lots of trouble for use. I think it's time simplify it by introducing a new mutex. We use the new mutex to prevent concurrent truncate_inode_pages(). There is no need to worry about race between buffered write and truncate_inode_pages(), because our "get caps" mechanism prevents them from concurrent execution.
