ufs: replace ll_rw_block()
mainline inclusion from mainline-v6.1-rc1 commit 6799b698 category: bugfix bugzilla: 187878,https://gitee.com/openeuler/kernel/issues/I5QJH9 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v6.1-rc2&id=6799b6983170c6dfdb2fcea8c97058557ea7b5b6 -------------------------------- ll_rw_block() is not safe for the sync read path because it cannot guarantee that submitting read IO if the buffer has been locked. We could get false positive EIO after wait_on_buffer() if the buffer has been locked by others. So stop using ll_rw_block() in ufs.
