libceph: change ceph_osdmap_flag() to take osdc

2016-05-30T21:00:22Z

For the benefit of every single caller, take osdc instead of map. Also, now that osdc->osdmap can't ever be NULL, drop the check. Signed-off-by: Ilya Dryomov

ceph: make logical calculation functions return bool

2016-05-25T23:15:39Z

This patch makes serverl logical caculation functions return bool to improve readability due to these particular functions only using 0/1 as their return value. No functional change. Signed-off-by: Zhang Zhuoyu

libceph: handle_one_map()

2016-05-25T23:12:27Z

Separate osdmap handling from decoding and iterating over a bag of maps in a fresh MOSDMap message. This sets up the scene for the updated OSD client. Of particular importance here is the addition of pi->was_full, which can be used to answer "did this pool go full -> not-full in this map?". This is the key bit for supporting pool quotas. We won't be able to downgrade map_sem for much longer, so drop downgrade_write(). Signed-off-by: Ilya Dryomov

libceph: allocate dummy osdmap in ceph_osdc_init()

2016-05-25T22:36:29Z

This leads to a simpler osdmap handling code, particularly when dealing with pi->was_full, which is introduced in a later commit. Signed-off-by: Ilya Dryomov

libceph: introduce ceph_osd_request_target, calc_target()

2016-05-25T22:36:26Z

Introduce ceph_osd_request_target, containing all mapping-related fields of ceph_osd_request and calc_target() for calculating mappings and populating it. Signed-off-by: Ilya Dryomov

libceph: pi->min_size, pi->last_force_request_resend

2016-05-25T22:36:26Z

Add and decode pi->min_size and pi->last_force_request_resend. These are going to be used by calc_target(). Signed-off-by: Ilya Dryomov

libceph: make pgid_cmp() global

2016-05-25T22:36:25Z

calc_target() code is going to need to know how to compare PGs. Take lhs and rhs pgid by const * while at it. Signed-off-by: Ilya Dryomov

libceph: rename ceph_calc_pg_primary()

2016-05-25T22:36:25Z

Rename ceph_calc_pg_primary() to ceph_pg_to_acting_primary() to emphasise that it returns acting primary. Signed-off-by: Ilya Dryomov

libceph: ceph_osds, ceph_pg_to_up_acting_osds()

2016-05-25T22:36:25Z

Knowning just acting set isn't enough, we need to be able to record up set as well to detect interval changes. This means returning (up[], up_len, up_primary, acting[], acting_len, acting_primary) and passing it around. Introduce and switch to ceph_osds to help with that. Rename ceph_calc_pg_acting() to ceph_pg_to_up_acting_osds() and return both up and acting sets from it. Signed-off-by: Ilya Dryomov

libceph: rename ceph_oloc_oid_to_pg()

2016-05-25T22:36:24Z

Rename ceph_oloc_oid_to_pg() to ceph_object_locator_to_pg(). Emphasise that returned is raw PG and return -ENOENT instead of -EIO if the pool doesn't exist. Signed-off-by: Ilya Dryomov
