commit 86a020cc
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=86a020cc7232c3defad370852415876bbe4576dc

--------------------------------

ll_rw_block() is not safe for the sync read path because it cannot
guarantee that always submitting read IO if the buffer has been locked,
so stop using it. We also switch to new bh_readahead() helper for the
readahead path.
