Sorry, we're seriously, seriously, seriously short on flags in the page struct and this patch is going to need one heck of a good case for it to be acceptable.
This was for the delayed allocation patchset, right; and by managing this at the page level that means we can't do this for block size < page size, I think...
There are already buffer head flags for delalloc (block to be allocated on flush) and unwritten (actual block allocated to a file but not yet written) in the vfs - shouldn't we be looking at using those?
Unless there is a clear path from this patchset to one that supports blocks < page, I'm hesitant about it... but I know I'm being a bit of an armchair quarterback here, and I'll try to set aside some time to give this a better look.
