Jeff Roberson d3b78f7337 - If we vrele() a dvp while the child is locked we can potentially deadlock ... when vrele() acquires the directory lock in the wrong order. Fix this via the following changes: - Keep the directory locked after VOP_LOOKUP() until we've determined what we're going to do with the child. This allows us to remove the complicated post LOOKUP code which determins whether we should lock or unlock the parent. This means we may have to vput() in the appropriate cases later, rather than doing an unsafe vrele. - in NDFREE() keep two flags to indicate whether we need to unlock vp or dvp. This allows us to vput rather than vrele in the appropriate cases without rechecking the flags. Move the code to handle dvp after we handle vp. - Remove some dead code from namei() that was the result of changes to VFS_LOCK_GIANT(). Sponsored by: Isilon Systems, Inc.		2005-04-09 11:53:16 +00:00
