Wendy,
What's the current status of these patches? I believe I have a
situation that could benefit from being able to release all NLM
locks
on an exported filesystem.
I think Bruce has queued the unlock patch for 2.6.26 (Bruce ?) ..
Not yet, for several reasons. First, there's two smaller problems
outstanding that I can recall:
- We should be matching on the superblock, not the vfs mount.
Otherwise, for example, the unlock will have no effect if it's
done from a private namespace, which I think will be
unexpected. Arguably this could result in revoking more locks
than necessary, but if the goal is to allow unmounting some
shared block device, then that's what we've got to do.
- Let's get the address types right. I think the concensus from
previous discussions was just to use in6_addr everywhere?
I thought the consensus was use in_addr everywhere, and let me worry
about converting these to in6_addr as part of the NLM IPv6 work.
