Compare and you'll see...  Block size on ext2 may be bigger than 1Kb;
->s_log_block_size gives the shift (1Kb -> 0, 2Kb -> 1, etc.)  Offset
0x18 in superblock, __le32...

Anyway, I've pushed that into vfs.git#master along with other minor stuff
right now; the last 5 commits in there are handling of ext2 and ext3 headers,
starting with "ext2: No longer export ext2_fs.h to user space" by
Thierry Reding, with the next 3 after it doing the move and trimming...
Should propagate to git.kernel.org in a few.

I've left the nfsd mess alone for now; it's too ugly to live, but I don't
want to trigger the bikeshedding from hell that happens every time somebody
brings pathconf() up.  Not worth bothering with, just to move two macros to
fs/ext2/ext2.h where they really belong...
