split read_seqretry_or_unlock(), convert d_walk() to resulting primitives Separate "check if we need to retry" from "unlock if we are done and had seq_writelock"; that allows to use these guys in d_walk(), where we need to recheck every time we ascend back to parent, but do *not* want to unlock until the very end. Lift rcu_read_lock/rcu_read_unlock out into callers. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
