34c5115a7f mount: implement -o nosymfollow, remove bogus -o union 
The (1 << 8) MS_ flag is MS_NOSYMFOLLOW, not MS_UNION.

MS_UNION did not ever exist.

768153bf8c mdev: add -v to increase log verbosity 
If logging to stderr and/or syslog the -v option can be given one or
more times to increase the log verbosity. If mdev is used as hotplug
helper the log level is fixed set to 2 if mdev.log is found an appended
because there is no possiblity to pass arguments to the hotplug helper.

e9003caf6d mdev: add syslog logging mode 
If mdev is run as daemon it should be possible to forward the debug
messages to syslog. This feature might be useful if mdev is run with -s
during boot too. OTOH it makes no sense for the daemon to log to
mdev.log. This can be handled by a syslog daemon way better. If the
daemon stays in the foreground due to -f, the messages are still written
to stderr as before.

d560030548 mdev: re-initialize if uevent messages were lost 
If the netlink read() failed with ENOBUFS we know that we have missed at
least one message due to a socket receive buffer overrun. The only way
how to recover is to drop the old socket, open a fresh one and make a
cold-plug scan of the current system state.

3cd55d49a2 mdev: increase netlink buffer sizes 
The socket receive buffer turned out to be too small for real world
systems. Use the same size as udevd to be on the safe side. As this is
just a limit and the memory is not allocated by the kernel until really
needed there is actually no memory wasted.
