Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client
Pull Ceph fixes from Sage Weil: "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." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/sage/ceph-client: (33 commits) rbd: re-submit flattened write request (part 2) rbd: re-submit write request for flattened clone rbd: re-submit read request for flattened clone rbd: detect when clone image is flattened rbd: reference count parent requests rbd: define parent image request routines rbd: define rbd_dev_unparent() rbd: don't release write request until necessary rbd: get parent info on refresh rbd: ignore zero-overlap parent rbd: support reading parent page data for writes rbd: fix parent request size assumption libceph: init sent and completed when starting rbd: kill rbd_img_request_get() rbd: only set up watch for mapped images rbd: set mapping read-only flag in rbd_add() rbd: support reading parent page data rbd: fix an incorrect assertion condition rbd: define rbd_dev_v2_header_info() rbd: get rid of trivial v1 header wrappers ...
