-->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

 For Win2k and later dynamic disks, you can for example use the ldminfo utility

 into it (cd linux-ldm-0.0.8) and change to the test directory (cd test).  You
