Sorry for the confusion.

This patch allows block-mount to mount xfs and f2fs on boot, I tested 
the patch and it works on my tp-link test router.

But afterwards I searched for similar checks for code in the same 
package/source folder, and yes, in fstools there are more 
filesystem-specific checks and operations.
Code for f2fs is already there, but code for xfs is not.

I didn't yet have the time to look more closely what that does exactly.

A list of files that must be changed to add xfs:

/mount_root.c there are filesystem type checks

/libfstools/find.c line 88 there is a filesystem type check.

/libfstools/libfstools.h line 25 there is a list of filesystem-specific 
variables

/libfstools/overlay.c line 198, another filesystem type check

/libfstools/rootdisk.c line 264, there is code to automatically format 
the overlay as either f2fs or ext4 if it isn't formatted correctly.

So while with my patch block mount will work with both f2fs and xfs, 
some other operations I didn't know about are not going to work on xfs.
