libceph: primary_temp infrastructure
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/<client>/osdmap, one 'primary_temp <pgid> <osd>' per line, e.g: primary_temp 2.6 4 Signed-off-by: Ilya Dryomov <ilya.dryomov@inktank.com> Reviewed-by: Alex Elder <elder@linaro.org>
