ovs-vswitchd occasionally needs to do some activities that may block
in the kernel unavoidably. This patch series changes ovs-vswitchd to
do these activities in a separate "worker process".
Ben Pfaff (12):
socket-util: Remove 'passcred' parameter from make_unix_socket().
socket-util: New function xset_nonblocking().
socket-util: Add functions for sending fds over Unix domain sockets.
util: Introduce "subprogram_name" to identify subprocesses and
threads.
daemon: Factor out code into new function
fork_and_wait_for_startup().
daemon: Factor out code into new function daemonize_post_detach().
vlog: Add VLOG_ABORT() to log and call abort().
worker: New library for breaking a daemon into multiple processes.
vlog: Use system calls instead of stdio to write log files.
vlog: Use worker process to write to log file.
shash: New functions smap_from_json(), smap_to_json().
system-stats: Run as part of worker process.
