ocfs2: fix a deadlock issue in ocfs2_dio_end_io_write()
The code should call ocfs2_free_alloc_context() to free meta_ac & data_ac before calling ocfs2_run_deallocs(). Because ocfs2_run_deallocs() will acquire the system inode's i_mutex hold by meta_ac. So try to release the lock before ocfs2_run_deallocs(). Fixes: af1310367f41 ("ocfs2: fix sparse file & data ordering issue in direct io.") Signed-off-by:Ryan Ding <ryan.ding@oracle.com> Acked-by:
