Revision c4a2d7fbec3029c8891a3ad5fceec2992096a3b7 authored by Michael Halcrow on 04 July 2008, 16:59:35 UTC, committed by Linus Torvalds on 04 July 2008, 17:40:05 UTC 
ecryptfs: remove unnecessary mux from ecryptfs_init_ecryptfs_miscdev()
 
The misc_mtx should provide all the protection required to keep the daemon
hash table sane during miscdev registration.  Since this mutex is causing
gratuitous lockdep warnings, this patch removes it.

 * Provides a minimal bust_spinlocks for architectures which don't have one of their own.

 * bust_spinlocks() clears any spinlocks which would prevent oops, die(), BUG()
