protection for i_size so you will need to use the BKL.
-->open() locking is in-transit: big lock partially moved into the methods.

Note: ext2_release() was *the* source of contention on fs-intensive
loads and dropping BKL on ->release() helps to get rid of that (we still
grab BKL for cases when we close a file that had been opened r/w, but that
