Subject: [process scheduler] Possible bug in context_swich()?
Date: Wed, 8 Sep 2010 17:28:17 +0200	[thread overview]
Message-ID: <201009081728.18227.fabio@metanix.org> (raw)

Dear List,

My previous mails to you have gone unheard... my last chance...

In context_switch() (in linux/kernel/sched.c), starting with release 2.6.33, 
two "unlikely" macro  have been changed to "likely". I think the previous 
logic was right while the latter is wrong.

In case I am missing something I, please, ask someone to explain the above 
mentioned inversion of logic through releases.

Thanks in advance.

fabio
