Mike Gerdts 8dbaca1300 bdev: use spinlock instead of mutex ... SPDK threads generally run on dedicated cores and locks should be rarely contended. Thus, putting a thread to sleep while waiting on a mutex does not free up CPU cycles for other pthreads or processes. Even when running in interrupt mode, lock contention should be low enough that spinlocks are a net win by avoiding context switches.
