Description HLjksuga inspur_group 2024-08-26 19:52:59 UTC 
Description of problem:
moves starting keep-alive from nvme_start_ctrl() into
nvme_init_ctrl_finish(), but don't move stopping keep-alive into
nvme_uninit_ctrl(), so keep-alive work can be started and keep pending
after failing to start controller, finally use-after-free is triggered if
nvme host driver is unloaded.

 This patch fixes kernel panic when running nvme/004 in case that connection
 failure is triggered, by moving stopping keep-alive into nvme_uninit_ctrl().

    This way is reasonable because keep-alive is now started in
    nvme_init_ctrl_finish().
