Hi, New version of the futex2 patches. These are actually tested and appear to work as expected. I'm hoping to get at least the first 3 patches merged such that Jens can base the io_uring futex patches on them. Changes since v0: - switched over to 'unsigned long' for values (Arnd) - unshare vmalloc_huge() (Willy) - added wait/requeue syscalls - fixed NUMA to support sparse nodemask - added FUTEX2_n vs FUTEX2_NUMA check to ensure the node_id fits in the futex - added selftests - fixed a ton of silly bugs
The changes look good to me, and the ABI should be fine without
special compat handler now. I sent a couple of minor comments, but
nothing important.
