H A D | devtmpfs.c | f1f76f86 Wed Dec 16 15:31:33 CST 2009 Thomas Gleixner <tglx@linutronix.de> 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.
