This series ends with a patch that avoids a race involving the initial read of an rbd image header and a change to the snapshot context. The problem occurs because the rbd client sets up its watch request on the header object *after* the initial header read, and if the snapshot context changes between them the kernel client snapshot context will not be up-to-date. The fix is to set up the watch before doing the initial header read. The recent patches, along with the patches in this series, make doing things in this order possible. -Alex [PATCH 1/5] rbd: move more initialization into rbd_dev_probe_image() [PATCH 2/5] rbd: define rbd_header_name() [PATCH 3/5] rbd: don't clean up watch in device release function [PATCH 4/5] rbd: don't bother checking whether order changes [PATCH 5/5] rbd: set up watch in rbd_dev_probe_image() -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
