[CRIU] [PATCH 0/3] Speed up recv_fd_from_peer()

[Kirill Tkhai]

Continuing Pavel Emelyanov's series "[PATCH 0/4] files: Sanitation"
and on top of it.

This series makes recv_fd_from_peer() do not call additional
ioctl() to examine data presence, and use MSG_DONTWAIT recvmsg()
parameter instead.

Tests are passed here:
