This patch adds a accessor function that allows determining if a mapped_device is in the deleting state and then adds this check to the target_message function. The result of this change would be that all targets would not be allowed to process messages post a mapped device entering the deleting state. As previously described in the email at the archive url provided below the target_message ioctl can result in new work / activities being started post the mapped device entering states that new target work could cause issues. http://permalink.gmane.org/gmane.linux.kernel.device-mapper.devel/10486 This patch depends on the previous patch that added dm_suspended_check due to proximity of changes in common files. --- Mike Anderson (3): dm: Add dm_deleting accesor function dm: Add accessor dm_table_md_deleting dm: Add deleting check to target_message drivers/md/dm-ioctl.c | 6 ++++++ drivers/md/dm-table.c | 6 ++++++ drivers/md/dm.c | 5 +++++ include/linux/device-mapper.h | 2 ++ 4 files changed, 19 insertions(+), 0 deletions(-) -- -andmike Michael Anderson <andmike@xxxxxxxxxxxxxxxxxx> -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
