[patch 1/3] FS_MBCACHE: don't needlessly make it built-in
Assume you have: - one or more of ext2/3/4 statically built into your kernel - none of these with extended attributes enabled and - want to add onother one of ext2/3/4 modular and with extended attributes enabled then you currently have to reboot to use it since this results in CONFIG_FS_MBCACHE=y. That's not a common issue, but I just ran into it and since there's no reason to get a built-in mbcache in this case this patch fixes it.
