* libceph: fixup includes in pagelist.hIlya Dryomov2014-12-17
| | | | | | | pagelist.h needs to include linux/types.h and asm/byteorder.h and not rely on other headers pulling yet another set of headers. Signed-off-by: Ilya Dryomov <idryomov@redhat.com>
* libceph: reference counting pagelistYan, Zheng2014-10-14
| | | | | | | this allow pagelist to present data that may be sent multiple times. Signed-off-by: Yan, Zheng <zyan@redhat.com> Reviewed-by: Sage Weil <sage@redhat.com>
* ceph: add pagelist_reserve, pagelist_truncate, pagelist_set_cursorGreg Farnum2010-10-20
| | | | | | | | These facilitate preallocation of pages so that we can encode into the pagelist in an atomic context. Signed-off-by: Greg Farnum <gregf@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>
* ceph: factor out libceph from Ceph file systemYehuda Sadeh2010-10-20
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>
