I note that all of these 25 patches have the same title, either they are
one change and would be in one patch, or more likely they are all
changing different bits of the kernel and as such could do with
meaningful titles.  For a start without that they could not be tested in
-mm as they will not load into Andrews patch tools.  Second reviewers
for the specific sub-systems or architectures touched may only look over
the patches that are relevant to them.  Without any clue in the title
they probabally won't bother.

Now its hard to be 100% sure that this spacing is what you have in your
copy as a lot of these patches appear at first viewing to be space munged
and wrapped probabally by your mailer.  BUT, this appears to be using
non-standard indent levels.  You will have much much much less resistance
if you follow the recommendations in Documentation/CodingStyle.  Also
you may want to check the emails as they have arrived at the LKML and
see if they are the same as your original, your mail reader may be
dammaging them.

This sounds very much like you are signing off your patch as per the
DCO.  If so then normally that would be done via a Signed-off-by: header
at the end of the leader, not down here.
