libceph: osdmap.h: Add missing format newlines

2015-04-20T15:55:35+00:00

To avoid possible interleaving, add missing '\n' to formats. Convert pr_warning to pr_warn while there. Signed-off-by: Joe Perches Signed-off-by: Ilya Dryomov

libceph: return primary from ceph_calc_pg_acting()

2014-04-05T04:08:14+00:00

In preparation for adding support for primary_temp, stop assuming primaryness: add a primary out parameter to ceph_calc_pg_acting() and change call sites accordingly. Primary is now specified separately from the order of osds in the set. Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder

libceph: switch ceph_calc_pg_acting() to new helpers

2014-04-05T04:08:13+00:00

Switch ceph_calc_pg_acting() to new helpers: pg_to_raw_osds(), raw_to_up_osds() and apply_temps(). Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder

libceph: ceph_can_shift_osds(pool) and pool type defines

2014-04-05T04:08:08+00:00

Bring in pg_pool_t::can_shift_osds() counterpart along with pool type defines. Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder

libceph: ceph_osd_{exists,is_up,is_down}(osd) definitions

2014-04-05T04:08:07+00:00

Sync up with ceph.git definitions. Bring in ceph_osd_is_down(). Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder

libceph: primary_affinity infrastructure

2014-04-05T04:08:02+00:00

Add primary_affinity infrastructure. primary_affinity values are stored in an max_osd-sized array, hanging off ceph_osdmap, similar to a osd_weight array. Introduce {get,set}_primary_affinity() helpers, primarily to return CEPH_OSD_DEFAULT_PRIMARY_AFFINITY when no affinity has been set and to abstract out osd_primary_affinity array allocation and initialization.

libceph: primary_temp infrastructure

2014-04-05T04:07:58+00:00

Add primary_temp mappings infrastructure. struct ceph_pg_mapping is overloaded, primary_temp mappings are stored in an rb-tree, rooted at ceph_osdmap, in a manner similar to pg_temp mappings. Dump primary_temp mappings to /sys/kernel/debug/ceph//osdmap, one 'primary_temp ' per line, e.g: primary_temp 2.6 4 Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder

libceph: generalize ceph_pg_mapping

2014-04-05T04:07:57+00:00

In preparation for adding support for primary_temp mappings, generalize struct ceph_pg_mapping so it can hold mappings other than pg_temp. Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder

libceph: split osdmap allocation and decode steps

2014-04-05T04:07:37+00:00

Split osdmap allocation and initialization into a separate function, ceph_osdmap_decode(). Signed-off-by: Ilya Dryomov Reviewed-by: Alex Elder

libceph: a per-osdc crush scratch buffer

2014-04-03T02:33:50+00:00

With the addition of erasure coding support in the future, scratch variable-length array in crush_do_rule_ary() is going to grow to at least 200 bytes on average, on top of another 128 bytes consumed by rawosd/osd arrays in the call chain. Replace it with a buffer inside struct osdmap and a mutex. This shouldn't result in any contention, because all osd requests were already serialized by request_mutex at that point; the only unlocked caller was ceph_ioctl_get_dataloc().
