From 5aea3dcd50215fa9563270251ad7323e2f2490ee Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Thu, 28 Apr 2016 16:07:26 +0200 Subject: libceph: a major OSD client update This is a major sync up, up to ~Jewel. The highlights are: - per-session request trees (vs a global per-client tree) - per-session locking (vs a global per-client rwlock) - homeless OSD session - no ad-hoc global per-client lists - support for pool quotas - foundation for watch/notify v2 support - foundation for map check (pool deletion detection) support The switchover is incomplete: lingering requests can be setup and teared down but aren't ever reestablished. This functionality is restored with the introduction of the new lingering infrastructure (ceph_osd_linger_request, linger_work, etc) in a later commit.
