Bob Peterson 6a2e275834 gfs2: use i_lock spin_lock for inode qadata ... [ Upstream commit 5fcff61eea9efd1f4b60e89d2d686b5feaea100f ] Before this patch, functions gfs2_qa_get and _put used the i_rw_mutex to prevent simultaneous access to its i_qadata. But i_rw_mutex is now used for many other things, including iomap_begin and end, which causes a conflict according to lockdep. We cannot just remove the lock since simultaneous opens (gfs2_open -> gfs2_open_common -> gfs2_qa_get) can then stomp on each others values for i_qadata. This patch solves the conflict by using the i_lock spin_lock in the inode to prevent simultaneous access.
