Actually, ext3 has been immune from most of the lock breakups in 2.5.
ext2 used to have a lot of problems with BKL contention resulting from
ext2_get_block() and some other assorted functions. Al Viro cleaned
these up in early 2.5, but ext3 never got the cleanup. It still scales
horribly, even 2.5.45.
