Byb1c097af8d(#10239), the receive buffer size for uevents was set by SO_RCVBUF at first, and fallback to use SO_RCVBUFFORCE. So, as SO_RCVBUF limits to the buffer size net.core.rmem_max, which is usually much smaller than 128MB udevd requests, uevents buffer size was not sufficient. This fixes the ordering of the request: SO_RCVBUFFORCE first, and fallback to SO_RCVBUF. Then, udevd's uevent buffer size can be set to 128MB. This also revert903893237a. Fixes #11314 and #10754.
