/**
 * futex() - SYS_futex syscall wrapper
 * @uaddr:	address of first futex
 * @op:		futex op code
 * @val:	typically expected value of uaddr, but varies by op
 * @timeout:	typically an absolute struct timespec (except where noted
 *		otherwise). Overloaded by some ops
 * @uaddr2:	address of second futex for some ops\
 * @val3:	varies by op
 * @opflags:	flags to be bitwise OR'd with op, such as FUTEX_PRIVATE_FLAG
 *
 * futex() is used by all the following futex op wrappers. It can also be
 * used for misuse and abuse testing. Generally, the specific op wrappers
 * should be used instead. It is a macro instead of an static inline function as
 * some of the types over overloaded (timeout is used for nr_requeue for
 * example).
 *
 * These argument descriptions are the defaults for all
 * like-named arguments in the following wrappers except where noted below.
