devtmpfs: Convert dirlock to a mutex
devtmpfs has a rw_lock dirlock which serializes delete_path and create_path. This code was obviously never tested with the usual set of debugging facilities enabled. In the dirlock held sections the code calls: - vfs functions which take mutexes - kmalloc(, GFP_KERNEL) In both code pathes the might sleep warning triggers and spams dmesg. Convert the rw_lock to a mutex. There is no reason why this needs to be a rwlock.
