behlendo cc7449ccd6 - Properly fix the debug support for all the ASSERT's, VERIFIES, etc can be
compiled out when doing performance runs.
- Bite the bullet and fully autoconfize the debug options in the configure
  time parameters.  By default all the debug support is disable in the core
  SPL build, but available to modules which enable it when building against
  the SPL.  To enable particular SPL debug support use the follow configure
  options:

  --enable-debug		Internal ASSERTs
  --enable-debug-kmem		Detailed memory accounting
  --enable-debug-mutex		Detailed mutex tracking
  --enable-debug_kstat          Kstat info exported to /proc
  --enable-debug-callb		Additional callb debug

behlendo c6dc93d6a8 By default disable extra KMEM and MUTEX debugging to aid performance.
They can easily be re-enabled when new stability issues are uncovered.

behlendo 404992e31a - Relocate 'stats_per' in to proper /proc/sys/spl/mutex/ directory
- Shift to spinlock for mutex list addition and removal

behlendo 4f86a887d8 Remaining issues fixed after reenabled mutex debugging.
- Ensure the mutex_stats_sem and mutex_stats_list are initialized
- Only spin if you have to in mutex_init

behlendo e8b31e8482 - Updated rwlock's to reside in a .c file instead of a static inline
- Updated rwlock's so they can be safely initialized in ctors.

behlendo 9ab1ac14ad Commit adaptive mutexes. This seems to have introduced some new
crashes but it's not clear to me yet if these are a problem with
the mutex implementation or ZFSs usage of it.

Minor taskq fixes to add new tasks to the end of the pending list.

Minor enhansements to the debug infrastructure.

behlendo bcd68186d8 New an improved taskq implementation for the SPL. It allows a
configurable number of threads like the Solaris version and almost
all of the options are supported.  Unfortunately, it appears to have
made absolutely no difference to our performance numbers.  I need
to keep looking for where we are bottle necking.

behlendo 937879f11d Update SPL to use new debug infrastructure. This means:
- Replacing all BUG_ON()'s with proper ASSERT()'s
- Using ENTRY,EXIT,GOTO, and RETURN macro to instument call paths

behlendo d61e12af5a - Add some spinlocks to cover all the private data in the mutex. I don't
think this should fix anything but it's a good idea regardless.

- Drop the lock before calling the construct/destructor for the slab
otherwise we can't sleep in a constructor/destructor and for long running
functions we may NMI.

- Do something braindead, but safe for the console debug logs for now.

behlendo c5fd77fcbf Just cleanup up an error case to avoid overspamming the console.
We get the stack once from the BUG() no reason to dump it twice.

behlendo 115aed0dd8 - Add more strict in_atomic() checking to the mutex entry
function just to be extra safety and paranoid.

- Rewrite the thread shim to take full advantage of the
new kernel kthread API.  This greatly simplifies things.

- Add a new regression test for thread_exit() to ensure
it properly terminates a thread immediately without
allowing futher execution of the thread.

behlendo f4b377415b Reorganize /include/ to add a /sys/, this way we don't need to
muck with #includes in existing Solaris style source to get it
to find the right stuff.
