This is some work I had nearly done a long time ago. It didn't even have a bug associated with it. I resurrected it over the weekend and ported it to the new code. It's basically cleanup though. For format 1 rbd images, when probing an image, header information for it is read in and translated directly into the rbd_dev->header structure. For an image refresh, instead, we use a stack structure to hold the translated header, and then in a second step we copy that into rbd_dev->header. This series gets rid of the local variable, and always just puts things directly into rbd_dev->header. It also simplifies probe and refresh for both format 1 and format 2, using a common rbd_dev_vX_header_info() function for both purposes. This set of patches, as well as the two single patches and series of six I just posted, are available in the "review/wip-rbd-cleanup-1" branch of the ceph-client git repository. -Alex [PATCH 1/7] rbd: set the mapping size and features later [PATCH 2/7] rbd: zero format 1 header structure earlier [PATCH 3/7] rbd: refactor rbd_header_from_disk() [PATCH 4/7] rbd: update in-core header directly [PATCH 5/7] rbd: simplify rbd_dev_v1_probe() [PATCH 6/7] rbd: get rid of trivial v1 header wrappers [PATCH 7/7] rbd: define rbd_dev_v1_header_info() -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
