vhost-user-blk: delay vhost_user_blk_disconnect
A socket write during vhost-user communication may trigger a disconnect event, calling vhost_user_blk_disconnect() and clearing all the vhost_dev structures holding data that vhost-user functions expect to remain valid to roll back initialization correctly. Delay the cleanup to keep vhost_dev structure valid. There are two possible states to handle: 1. RUN_STATE_PRELAUNCH: skip bh oneshot call and perform disconnect in the caller routine. 2. RUN_STATE_RUNNING: delay by using bh BH changes are based on the similar changes for the vhost-user-net device: commit e7c83a885f865128ae3cf1946f8cb538b63cbfba "vhost-user: delay vhost_user_stop" Signed-off-by: Dima Stepanov <dimastep@yandex-team.ru> Message-Id: <69b73b94dcd066065595266c852810e0863a0895.1590396396.git.dimastep@yandex-team.ru> Reviewed-by: Michael S.
