Subject: fs corruption in 2.4.0-test11?

I just need a sanity check - do other pages/blocks sometimes show up in
recently created files in 2.4.0-test11?

I have a (so far) non-reproducible case where the wrong data showed up in
a new file. The nice part is that it was when I was imploding a large
BitKeeper patch so I can run the test case over and over if that would
help find it.

Mmmm. Yes. I think the final fixes for this went into v2.4.0-test12pre5,
but since there's a test13-pre3 out that needs testing, go for that one
directly... :^)

If you can reproduce it on test13-pre3, we have something to worry
about, if not, feel happy; one bug less to worry about.

2.4.0-test13-pre ate /usr/src at home (i686, RH7 + updates): Again, files
turn into directories, massive ammounts of duplicate blocks, ... Not as bad
as 2.4.0-test11 used to be (/ survived this time ;-)

ext2, ext3 or reiserfs (or xfs or jfs or ...)

Still, this sounds bad to me. Have you reported this to Linus+Alexander
Viro? Oh, never mind, I'm CC:ing them now.

Nope, didn't. Thanks!
