I built the 3.10-rc rbd module for a 3.8 kernel yesterday, and only had one thing to add (I know I'm reviving an old thread). There is one folder missing from the original list of files to use: include/linux/crush/* That would bring everything to: include/keys/ceph-type.h include/linux/ceph/* include/linux/crush/** fs/ceph/* net/ceph/* drivers/block/rbd.c drivers/block/rbd_types.h RBD built without a hitch. Getting CephFS to build was going to be a bit more work, but I didn't need it so I just skipped it. - Travis On Mon, Apr 29, 2013 at 8:41 PM, James Harper <james.harper@xxxxxxxxxxxxxxxx> wrote: >> >> I'm probably not the only one who would like to run a >> distribution-provided kernel (which for Debian Wheezy/Ubuntu Precise is >> 3.2) and still have a recent-enough Ceph kernel client.
