Looks like a lot of places could be converted to use
"struct xfs_dir2_sf_hdr" rather than the typedef, but
it's not worth re-posting for that. (Plus I suspect
such changes may be in forthcoming patches...)
Another few dumb little suggestions below--mostly
regarding a consistent naming scheme--but otherwise
this looks good.

I think I like the name "hdr" better than "sfp";
was it just too widespread a change to do a
similar rename elsewhere? (xfs_dir2_block_to_sf()
uses "sfhp" already, though I like just "hdr".)
