Without looking at the gfs code, I cannot give you definite answers, but:

In fs.h:

You need to define BH_Delay as some value not already used - I presume
GFS adds a new buffer flag.

You need to add the writepage_nounlock and toss_page methods to the
address_space operations vector, just do it, no other change would
be needed.

In vmscan.c:

Hard to say, what does the code look like at this location?

In ksyms.c

Just add in the line
