Subject: shared subtree query
Date: Wed, 31 Aug 2005 17:00:09 -0700	[thread overview]
Message-ID: <1125532808.10823.105.camel@localhost> (raw)

Ok. I have shared subtree patches getting ready for review. I have
totally revamped the code from what I had sent last time, incorporating
all valuable comments Miklos had made. Offcourse I am yet to finish a
document that Andrew Morton had requested.

The patch snapshot at:
http://www.sudhaa.com/~ram/readahead/sharedsubtree
and the latest set of working patches are at:
http://www.sudhaa.com/~ram/readahead/sharedsubtree/shared.0831.1

Before I formally send the patches for a review, I have bumped into a
small issue, and I am not sure about the behavior.

Al Viro's RFC at http://lwn.net/Articles/119232/ says

5. umount
  unmount everything that gets propagation from victim

Its hard to interpret what victim means. There can be two
interpretations to this.

1) the mount that got unmounted
2) the mount whose child got unmounted

I think its natural to assume (2), but (1) also makes sense sometimes.
Can somebody shed some light on this?  Al Viro: please?

Thanks for your help,
RP
