mm, sl[aou]b: Use a common mutex definition

2012-07-09T09:13:41Z

Use the mutex definition from SLAB and make it the common way to take a sleeping lock. This has the effect of using a mutex instead of a rw semaphore for SLUB. SLOB gains the use of a mutex for kmem_cache_create serialization. Not needed now but SLOB may acquire some more features later (like slabinfo / sysfs support) through the expansion of the common code that will need this.

All allocators have some sort of support for the bootstrap status. Setup a common definition for the boot states and make all slab allocators use that definition. Reviewed-by: Glauber Costa Reviewed-by: Joonsoo Kim Signed-off-by: Christoph Lameter Signed-off-by: Pekka Enberg
