Previously I submitted a patch for "blk: request botched" on floppy
write. While the patch did make the floppy work, Jens mentioned
that an underlying error still existed. This spurred me on to look a
little deeper and finally i found the root cause.
There is a bug in "ll_rw_blk.c" handling partial bvec submissions.
For whatever reason the floppy driver was triggering it more than
other users. Note that with the attached patch, my previous
floppy_ patch is no longer needed.
Cheers,
Sean
