37de5a0d83 * The rw_lock now behaves just like a recursive locker if KDEBUG_RW_LOCK_DEBUG
is defined to 1; this allows asserting the read lock case, too.
* Added ASSERT_{READ|WRITE}_LOCKED_RW_LOCK() macros. The read assertion is only
  working when KDEBUG_RW_LOCK_DEBUG is defined to 1, the write assertion works
  always.

78b32dd026 * The rw_lock is now able to nest read/write locks when you have a write lock.
It follows the semantics of the BFS R/W lock, though, that is, if you unlock
  your write lock before the read locks, the read locks effectively become
  write locks, too.
* Added a mutex_transfer_lock() function that will allow you to unlock a mutex
  in a different thread than the one which locked it (only matters if KDEBUG
  is enabled, though).

589f1a9133 * Made the private kernel locking primitives available to file systems as well.
* Applied Korli's mutex_unlock() fix to block_cache.cpp.
* Removed block_cache_priv.h, as it's no longer needed (moved its definitions
  into block_cache.cpp, as in the kernel file).
