*	Reengineer subr_unit	Poul-Henning Kamp	2005-03-08	1	-287/+511
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Add support for passing in a mutex. If NULL is passed a global subr_unit mutex is used. Add alloc_unrl() which expects the mutex to be held. Allocating a unit will never sleep as it does not need to allocate memory. Cut possible range in half so we can use -1 to mean "out of number". Collapse first and last runs into the head by means of counters. This saves memory in the common case(s). Notes: svn path=/head/; revision=143283

*	Add a new API for allocating unit number (-like) resources.	Poul-Henning Kamp	2004-09-30	1	-0/+597
	Allocation is always lowest free unit number. A mixed range/bitmap strategy for maximum memory efficiency. In the typical case where no unit numbers are freed total memory usage is 56 bytes on i386. malloc is called M_WAITOK but no locking is provided (yet). A bit of experience will be necessary to determine the best strategy. Hopefully a "caller provides locking" strategy can be maintained, but that may require use of M_NOWAIT allocation and failure handling. A userland test driver is included.
