This separates out the DeviceSet logic a bit better from the raw device mapper operations. devicemapper: Serialize addess to the devicemapper deviceset This code is not safe to run in multiple threads at the same time, and neither is libdevmapper. DeviceMapper: Move deactivate into UnmountDevice This way the deactivate is atomic wrt othe device mapper operations and will not fail with EBUSY if someone else starts a devicemapper operation inbetween unmount and deactivate. devmapper: Fix loopback mounting regression Some changes were added to attach_loop_device which added a perror() in a place that caused it to override errno so that a later errno != EBUSY failed. This fixes that and cleans up the error reporting a bit. devmapper: Build on old kernels without LOOP_CTL_GET_FREE define |
