Hi Chris, This is the extent of my current queue of Btrfs snapshot/subvol/commit stuff. Most of these were posted several months ago. Can be sent upstream during this merge window? Not having this functionality is becoming a bit of a roadblock for our efforts to keep the Ceph data in a consistent state. These patches are also available from

This was originally intended just for nouveau, but has since been expanded to all DRM drivers. Changes since previous version: - Fix documentation error that got noticed by the kbuild bot in "drm/dp_mst: Pass entire connector to

Hi everyone, I described the reflink operation at the Linux Storage & Filesystems Workshop last month. Originally implemented as an ocfs2-specific ioctl, the consensus was that it should be a syscall from the get-go. Here's some first-cut patches. For people who have not seen reflink, either at LSF or on the ocfs2 wiki, the first patch contains Documentation/filesystems/reflink.txt to

Hi all, So I have finally finished the v1 of reflink for ocfs2. It has some bugs that I am still investigating, but the schema is almost there. So I'd like to send it out first for review. And Tristan and I will continue to work on the stability of the code. The general information for reflink, please see http://oss.oracle.com/osswiki/OCFS2/DesignDocs/Reflink. For the design doc, please
