Use CONFIG_EXT4_FS instead of CONFIG_EXT3_FS in all of the defconfigs (2025-10-13 21:50:40 -0400)
----------------------------------------------------------------
Ext4 bug fixes for 6.18-rc2, including
* Fix regression caused by removing CONFIG_EXT3_FS when testing some
very old defconfigs
* Avoid a BUG_ON when opening a file on a maliciously corrupted file system
* Avoid mm warnings when freeing a very large orphan file metadata
* Avoid a theoretical races between metadata wrtteback and checkpoints.
(It's very hard to hit in practice, since the race requires that the
writeback take a very long time.)
