Details

In the Linux kernel, the following vulnerability has been resolved: f2fs: compress: fix to call f2fswaitonpagewriteback() in f2fswriterawpages() BUGON() will be triggered when writing files concurrently, because the same page is writtenback multiple times. 1597 void folioendwriteback(struct folio *folio) 1598 { ...... 1618 if (!__folioendwriteback(folio)) 1619 BUG(); ...... 1625 } kernel BUG at mm/filemap.c:1619!

All pagelocks were released in f2fswriterawpages(), but whether the page was in the writeback state was ignored in the subsequent writing process. Let's fix it by waiting for the page to writeback before writing.
