2013-02-18libceph: update ceph_fs.hAlex Elder1-8/+24
Update most of "include/linux/ceph/ceph_fs.h" to match its user space counterpart in "src/include/ceph_fs.h" in the ceph tree. Everything that has changed is either: - added definitions (therefore no real effect on existing code) - deleting unused symbols - added or revised comments There were some differences between the struct definitions for ceph_mon_subscribe_item and the open field of ceph_mds_request_args; those differences remain.

2012-07-30libceph: move feature bits to separate headerSage Weil1-14/+0
This is simply cleanup that will keep things more closely synced with the userland code. Signed-off-by: Sage Weil <sage@inktank.com> Reviewed-by: Alex Elder <elder@inktank.com> Reviewed-by: Yehuda Sadeh <yehuda@inktank.com>
2012-05-07ceph: drop support for preferred_osd pgsSage Weil1-2/+2
This was an ill-conceived feature that has been removed from Ceph. Do this gracefully: - reject attempts to specify a preferred_osd via the ioctl - stop exposing this information via virtual xattrs - always fill in -1 for requests, in case we talk to an older server - don't calculate preferred_osd placements/pgids Reviewed-by: Alex Elder <elder@inktank.com> Signed-off-by: Sage Weil <sage@inktank.com>
2011-05-24ceph: use LOOKUPINO to make unconnected nfs fh more reliableSage Weil1-0/+1
If we are unable to locate an inode by ino, ask the MDS using the new LOOKUPINO command. Signed-off-by: Sage Weil <sage@newdream.net>
2011-03-21ceph: update common header filesYehuda Sadeh1-4/+15
This updates the common header files used by the different ceph related modules. Specifically it adds definitions required by the rbd watch/notify feature. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net>
2011-01-12ceph: add dir_layout to inodeSage Weil1-3/+13
Add a ceph_dir_layout to the inode, and calculate dentry hash values based on the parent directory's specified dir_hash function. This is needed because the old default Linux dcache hash function is extremely week and leads to a poor distribution of files among dir fragments. Signed-off-by: Sage Weil <sage@newdream.net>

2010-10-20ceph: factor out libceph from Ceph file systemYehuda Sadeh1-0/+728
This factors out protocol and low-level storage parts of ceph into a separate libceph module living in net/ceph and include/linux/ceph. This is mostly a matter of moving files around. However, a few key pieces of the interface change as well: - ceph_client becomes ceph_fs_client and ceph_client, where the latter captures the mon and osd clients, and the fs_client gets the mds client and file system specific pieces. - Mount option parsing and debugfs setup is correspondingly broken into two pieces. - The mon client gets a generic handler callback for otherwise unknown messages (mds map, in this case). - The basic supported/required feature bits can be expanded (and are by ceph_fs_client). No functional change, aside from some subtle error handling cases that got cleaned up in the refactoring process. Signed-off-by: Sage Weil <sage@newdream.net>
