Sigh. So you're only looking at the _second_ posting of them, not the first.
Here's the message, minus the patch.

To which I had this _single_ response:

And "it doesn't seem to apply" is precisely what I expected with the patch
because of the conflicts with _other_ work which was in progress, and as I
was asking in the original message about the _idea_, that is perfectly

I think I've just proven above that it was Sunday, not Monday.

Yes. Committed on _Sunday_ before I sent out the _first_ message which
I've included above. Then tweaked and after Ralf's response, the series
was then posted on _Monday_ in full. Then John responded with his ack,
which caused the amendment on _Tuesday_ morning.

And then _36_ further hours passed before the branch was merged into
for-next on _Wednesday_ _evening_. So, Sunday evening to Wednesday
evening. Three times 24 is 72 hours, which is what I corrected you to.

Are you _seriously_ trying to tell me that you have a problem with a commit
dated 18 hours after being mailed out? If so, you're being rediculous here.

Obviously I shouldn't have added John's ack, which was sent during Monday
nighttime to the commit so quickly, but instead waited a week before doing
so. Had I done that you wouldn't be complaining about "24 hours" or "18

Well, stop making such a big deal about "24 hours" or "18 hours" then,
but start realizing that the commit date is actually a total
_irrelevance_ to the time that it appeared in linux-next.

Your continual waving of that point, and reduction in time period, just
shows that you're trying to make this a _political_ issue, not a technical
or social one, which again is born out by the amount of people _you_ added
to this thread.

Well, the fact that I messed up the function name was unfortunate and
should've been caught locally, which I appologize for. I would have
thought that much was obvious, but since you seem to believe that I
_intentionally_ broke the x86 build.

Anyway, the issue has been resolved _properly_ over the weekend, off-list,
between Thomas and myself, in a way that results in no conflicts being
exposed in any tree.
