Interesting domain name.

I've just re-reviewed the 2.4.16 -> 2.4.18 diffs. There's really
nothing there which could explain this. We have:

- lots of s/bread/sb_bread/etc. Which is rather unfortunate because
it complicates any attempt to back out to 2.4.16's ext3.

- A bug fix for locking journal buffers (the infamous "request_list
destroyed" bug)

- Some error-path-only code which remounts the fs readonly rather than taking
down the machine when the unexpected happens.

I'd be suspecting this, frankly. Might be an IDE failure.
