For writes, we (1) never start any new operations after we've cleaned up the file descriptor tables so (2) after we're done with do_fsync() we never touch ->f_mapping again. But for reads, I think there's a problem if we're in do_generic_mapping_read() doing invalidate_inode_pages2() is not enough because we're hanging on to the real mapping. Hmm.
