filemap: remove use of wait bookmarks
mainline inclusion from mainline-v6.7-rc1 commit b0b598ee08f9759b70971e297cf7ddd3eaaa5245 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I93R1D CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=b0b598ee08f9759b70971e297cf7ddd3eaaa5245 -------------------------------- The original problem of the overly long list of waiters on a locked page was solved properly by commit 9a1ea439 ("mm: put_and_wait_on_page_locked() while page is migrated"). In the meantime, using bookmarks for the writeback bit can cause livelocks, so we need to stop using them.
