Subject: FS_MBCACHE: don't needlessly make it built-in
From: Adrian Bunk <bunk@xxxxxxxxxx>
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.
