BTW, I built that kernel without the patch you mentioned in
http://thread.gmane.org/gmane.linux.kernel.mm/90911/focus=91153
("buffer_heads_over_limit can put kswapd into reclaim, but it's ignored
[...]) It looked to me like that patch was only meant for debugging. Let
me know if that was wrong. Ohh, and I didn't update to a fresher
mainline checkout yet to make sure the base for John's testing didn't
change.

Ah, yes, the ApplyPatch is commented out.

I think we want that upstream as well, but it's not critical.

Sorry, it had no "Singed-off-by", so I assumed it was just for debugging.

Not rebasing sounds reasonable to me to verify the patch.  It might be
worth testing that the final version that will be 3.8 still works for
John, however, once that is done.  Just to be sure.

Just to be sure, I yesterday built a rc8 kernel with the patch
referenced above and the one that is not yet merged (these two, to be
precise: http://thread.gmane.org/gmane.linux.kernel.mm/90911/focus=91153
http://thread.gmane.org/gmane.linux.kernel.mm/90911/focus=91300
; all the others patches my kswap test kernels contained earlier were
afaics merged a few days ago) and mentioned it in the Fedora bug report.
John gave them a try and  in
https://bugzilla.redhat.com/show_bug.cgi?id=866988#c65 reported "No
problems so far.  I'll check back again in ~24hours."

CU, Thorsten
