Yes, I contacted stable@kernel.org regarding bug number 550898. But
this situation is a little bit different. With 550898, IBM wrote
a single git commit to fix a single bug. Asking for that commit to
be back-ported was a routine matter. But for bug number 607416 it appears
that they didn't do it that way. Thanks to the information provided by
Jonathan Nieder, I was able to find the commit for this bug. It is
listed below:

-----

commit f85cca6b25971a09efbe4c6a3ae405d40c8f86da
Merge: 6f576d5 dd30ac3
Author: Linus Torvalds <torvalds@linux-foundation.org>

Merge branch 'for-linus' of git://git390.marist.edu/pub/scm/linux-2.6

* 'for-linus' of git://git390.marist.edu/pub/scm/linux-2.6:
[S390] net: provide architecture specific NET_SKB_PAD
[S390] atomic: use inline asm
[S390] correct ipl parameter block safe guard
[S390] atomic: use ACCESS_ONCE() for atomic_read()
[S390] dasd: correct device table

-----

As far as I can tell, only the last line is applicable to this bug.

[S390] dasd: correct device table

In other words, instead of producing a single fix for a single bug,
they threw the fix in with several other miscellaneous fixes and enhancements.
I wish IBM hadn't done it that way, but they did. Therefore, I am unsure
as to how to proceed. Do I ask stable@kernel.org to port the whole commit?
(It may have dependencies on previous commits and get complicated rather
quickly.) Or do I ask them to cherry pick that one-line change in
drivers/s390/block/dasd_eckd.c? I could use some advice here.
