Konstantin Belousov e7f9b74438 Resolve the devfs deadlock caused by LOR between devfs_mount->dm_lock and ... vnode lock in devfs_allocv. Do this by temporary dropping dm_lock around vnode locking. For safe operation, add hold counters for both devfs_mount and devfs_dirent, and DE_DOOMED flag for devfs_dirent. The facilities allow to continue after dropping of the dm_lock, by making sure that referenced memory does not disappear.
