linux-user: Support the accept4 socketcall
PATCH 1/1 linux-user: Support the accept4 socketcall
From: André Hentschel <[email protected]>

See https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/include/uapi/linux/net.h for the values. Not entirely sure how to implement recvmmsg and sendmmsg...
PS: I hit send to early on the last attempt, sry.

The patch appears to be okay, but I'm not sure why you're sending it to -trivial, linux-user has an active maintainer (Riku, who has been Cc'ed too). If he agrees I can apply this to -trivial.
