It would be nice if we separated the buffer-cache storage pages from the pagecache buffer-using ones and from the swap ones - logics is seriously different and using the same code for all of them... Not good. We can distinguish between them just by looking at ->mapping, AFAICS.
BTW, I suspect that combination of partial block_flushpage() with block_truncate_page() should be address_space method (different for NFS, etc., indeed). Then truncate_inode_pages() would become much simpler ("get rid of pages that went off-limits" rather than "... and do some part of the work on the partial page". Oh, and block_flushpage() would be simpler that way.
