Patches 1-3 fix races between device removal and notify processing. Patch 2 has an improved summary, fixes reference counting, and renames the function as suggested by Alex.
Patch 3 is a reworked and simplified version that uses the existing rbd_dev->flags and lock instead of adding new ones. It also restricts where it holds the lock to avoid an inversion with bdev->lock. Patch 4 is the same. Patch 5 fixes an inconsistency noticed by Alex in his review of patch 4. Josh Durgin (5): rbd: complete notifies before cleaning up osd_client and rbd_dev rbd: make rbd_obj_notify_ack() synchronous rbd: fix use-after free of rbd_dev->disk rbd: ignore unmapped snapshots that no longer exist rbd: fix error handling from rbd_snap_name() drivers/block/rbd.c | 71 ++++++++++++++++++++++++++++++++++++++------------- 1 files changed, 53 insertions(+), 18 deletions(-) -- 1.7.2.5 -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
