Joseph Qi 512f62acbd ocfs2: fix race between dio and recover orphan ... During direct io the inode will be added to orphan first and then deleted from orphan. There is a race window that the orphan entry will be deleted twice and thus trigger the BUG when validating OCFS2_DIO_ORPHANED_FL in ocfs2_del_inode_from_orphan. ocfs2_direct_IO_write ... ocfs2_add_inode_to_orphan >>>>>>>> race window. 1) another node may rm the file and then down, this node take care of orphan recovery and clear flag OCFS2_DIO_ORPHANED_FL. 2) since rw lock is unlocked, it may race with another orphan recovery and append dio. ocfs2_del_inode_from_orphan So take inode mutex lock when recovering orphans and make rw unlock at the end of aio write in case of append dio.
