sorry..hit send key a bit too fast...here's the bit of code I wanted
to quote:
fs/ext2/ialloc.c:       inode->i_blksize = PAGE_SIZE;   /* This is the optimal IO size (for stat), not the fs block size */

Does this really mean ext2 tries to do IO in page size chunks?
I'll assume it does (usually) unless told otherwise since 4k vs 16k
block size on 16k page size gave basically the same result.
