User space programs like udevd may try to read to partitions at the same time the driver detects a namespace is unusable, and may deadlock if revalidate_disk() is called while such a process is waiting to enter the frozen queue. On detecting a dead namespace, move the disk revalidate after unblocking dispatchers that may be holding bd_butex. changelog Suggested-by: Keith Busch <kbusch@kernel.org> Signed-off-by: Balbir Singh <sblbir@amzn.com> Reviewed-by: Keith Busch <kbusch@kernel.org> Signed-off-by: Sagi Grimberg <sagi@grimberg.me> |
