5337ad4a43 Make userspace blkdev cleanup code more robust. 
The existing cleanup code would silently cancel disk IO requests, if
somehow the calling code did not wait for completion.  This code now
tracks requests and will bug if any are lost.

76e147d0a9 Fix refcount bug in blkdev and timer kthreads. 
The shutdown code in d79d57e and b20e160 had a race condition during
shutdown, due to not owning a reference on the associated task_struct
while the associated threads shut themselves down.

Patch over this by taking an appropriate reference.

ff4d082246 Change preempt_disable() etc. to use a recursive mutex. 
This is part of the userspace implementation of the kernel APIs for
bcachefs-tools. The previous implementation just provided a barrier, but
this isn't sufficient to make the associated percpu implementation safe.

e1ed5557bf Add valgrind handling: data read from io_submit was not being marked 
properly. Manually mark it.

This might be better done by improving the valgrind wrapper for
io_submit.
