Hi Linus,
Please pull the following patches from
git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client.git for-linus
Yes, this is a much larger pull than I would like after -rc1. There are a
few things included:
- a few fixes for leaks and incorrect assertions
- a few patches fixing behavior when mapped images are resized
- handling for cloned/layered images that are flattened out from
underneath the client
The last bit was non-trivial, and there is some code movement and
associated cleanup mixed in. This was ready and was meant to go in last
week but I missed the boat on Friday. My only excuse is that I was
waiting for an all clear from the testing and there were many other shiny
things to distract me.
Strictly speaking, handling the flatten case isn't a regression and could
wait, so if you like we can try to pull the series apart, but Alex and I
would much prefer to have it all in as it is a case real users will hit
with 3.10.
Thanks!
sage
