For ->writepage() - nothing. It _is_ asynchronous and it _can_ fail. Due to failing allocations, IO errors, whatever.
Now, the fs consistency stuff is a different story. Fixes had been in -ac since before 2.4.0 and I distinctly remember at least one of 3 area getting synced with -linus. My fault - I assumed that the whole patch went there at that point. I'll try to dig the rest out.
2.4.9-ac* is probably a good starting point - they are in generic_file_write() and in __block_write_full_page()
