What exactly does the POSIX locking option do?
I know what it does NOT do: flock() the files a Windows machine has
locked. When for example a file is locked on server side (Linux, I
tried all three Debian samba releases from stable, testing and
unstable), notepad on Windows still opens it. If it however is locked by
a Windows application on another computer, notepad refuses.
Does "posix locking" perhaps map SMB locks to something else than
flock()?
