The filename of the patch is: f2fs-defer-readonly-check-vs-norecovery.patch and it can be found in the queue-6.14 subdirectory.

If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

I already replied to the AUTOSEL email on 5/5 saying that this is not a bug fix and should not be in the stable tree, but here we are.

commit 442e4090bb78d5dce4506a591214ce2447d6ea50 Author: Eric Sandeen sandeen@redhat.com Date: Mon Mar 3 11:12:17 2025 -0600

f2fs: defer readonly check vs norecovery

[ Upstream commit 9cca49875997a1a7e92800a828a62bacb0f577b9 ] Defer the readonly-vs-norecovery check until after option parsing is done so that option parsing does not require an active superblock for the test. Add a helpful message, while we're at it. (I think could be moved back into parsing after we switch to the new mount API if desired, as the fs context will have RO state available.)
