Jaswinder,

Let me transcribe what happened:

[ Jaswinder misunderstands a patch and asks a rather stupid question 
  in a demanding tone and does not go into any level of detail why 
  he thinks the patch is wrong. Just a single look into the source 
  code file in question would have shown him his mistake. ]

[ Thomas, the genirq maintainer, points out Jaswinder's error 
  calmly. ]

[ Thomas also asks Jaswinder to think things through before wasting 
  other people's time. ]

[ Jaswinder is being difficult: he writes that Thomas "somehow"
  applied the patch - ignoring the fact that Thomas is the 
  maintainer of this code.

  Jaswinder is also suggesting in a condescending tone that Thomas
  does not understand the issue - while the code is perfectly fine 
  and it is Jaswinder who is trivially wrong.

  Wasting more of Thomas's time. ]

[ Thomas, understandably, being into the 4th mail of a thread that 
  should not have happened at all, is getting annoyed. ]

> > That patch applies fine on master as well.

[ Thomas points out another mistake in Jaswinder's argument. ]

[ Jaswinder shows evidence of even more stupidity: he points out to 
  Thomas that a function changed its name, forgetting two things: 
  that 1) it is irrelevant and 2) Thomas did the rename in question. ]

[ Thomas is really annoyed at Jaswinder writing wrong, 
  irrelevant, time wasting mails without showing any sign of 
  understanding the issues and without admitting fault. ]

[ Jaswinder, still not admitting his fault, compounds his mistakes
  by being even more condescending. ]

Jaswinder, this is really not an acceptable pattern of behavior on 
lkml.
