mainline inclusion from mainline-v5.15 commit 0e59a87ee619915c2eb189eb232a972c276681fb category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I4G67J?from=project-issue CVE: NA
----------------------------------------------------------------------
Initializing should be as close as possible when we use it so that we do not need to scroll up to see what is happening.
Also bdev_get_queue() can never return NULL so we do not need to check for !rq.
