mainline inclusion from mainline-v5.16 commit a1c2f7e7 category: bugfix bugzilla: 182378 https://gitee.com/openeuler/kernel/issues/I4DDEL Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a1c2f7e7f25c9d35d3bf046f99682c5373b20fa2 --------------------------- For fixing queue quiesce race between driver and block layer(elevator switch, update nr_requests, ...), we need to support concurrent quiesce and unquiesce, which requires the two call to be balanced. __bind() is only called from dm_swap_table() in which dm device has been suspended already, so not necessary to stop queue again. With this way, request queue quiesce and unquiesce can be balanced.
