(this patch probably doesn't apply to the current tree; it's done against
a bit of a mishmash tree in my current working directory. it's not for
applynig, but for commentary).
Matthhew,
I tested again with v4.1-rc7, bug still present.
I was able to apply the patch (at offsets -10, -1, -8 for
fs/block_dev.c, fs/mpage.c, and mm/page_io.c). That test has been
running without error for 14 hours. The bug would occur with this setup
within 10 minutes.
Thanks.
Charles Bertsch
