This is all bikeshedding, of course: what actually matters is making that lock exclusive once again :)
Just realized that for exclusive (aka write) lock, the FD must be opened for writing (working on patches for the following report [1] and been experimenting a bit and that's what I'm seeing).
Good point, but luckily not related to flock(2).
That seems to be the case: according to flock(2), A shared or exclusive lock can be placed on a file regardless of the mode in which the file was opened. Michal, does that sound reasonable to you? -- Andrea Bolognani / Red Hat / Virtualization
