Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> jbd2: fix deadlock in jbd2_journal_cancel_revoke()<br /> <br /> Commit f76d4c28a46a ("fs/jbd2: use sleeping version of<br /> __find_get_block()") changed jbd2_journal_cancel_revoke() to use<br /> __find_get_block_nonatomic() which holds the folio lock instead of<br /> i_private_lock.
