Fine, I was just looking at it from the VFS point of view, not the
specific filesystem.  In the worst case, a filesystem can always simply
defer marking the buffer as dirty until after the locking window has
passed, so there's obviously no fundamental problem with having a
blocking mark_buffer_dirty.  If we want a non-blocking version too, with
the requirement that the filesystem then to a manual rebalance once it
is safe to do so, that will work fine too.
