Ok, the patch is reasonably big, mainly due to a new architecture (cris)
and some updates to others (arm and mips).
But what's interesting here are actually three very small patches:
- mm/memory.c (PageReserved() check): this could corrupt the shared zero
page if you used direct IO, and thus make your system unusable
- elevator fix (another missed re-initialization in __make_request(), and
this time we made sure to check that everything else _is_ initialized)
- IDE driver multi-mode write fix (ide_multwrite()).
The first would only hit you if you used raw IO (and had some unlucky
timing etc), and very few people do.
The second can cause disk corruption with pretty much any disk (seen at
least on SCSI under heavy load). Not necessarily easy to trigger, but
still..
The third can cause disk corruption on IDE disks if you are using PIO
writes with multi-mode and irq unmasking enabled.
All three are quite nasty, but not all that easy to trigger (and have been
around for ages in the 2.3.x series - which only goes to show you how
important it is to have gotten a lot of new testers). Special thanks go to
Russell King for debugging the IDE driver thing with some heroic tracing
stuff.
I'd like people to test it out a bit before I'll make a real 2.4.2
release, but the three bugs do make it clear that a 2.4.2 will have to
happen soonish. The rest of the patches are quite cosmetic in comparison
even if they are much bigger..
