Subject: Re: [KJ] (re) audit return code handling for kernel_thread [3/3]
Date: Sat, 29 Jul 2006 20:20:24 +0000	[thread overview]
Message-ID: <20060729202024.GD8574@localhost.localdomain> (raw)
In-Reply-To: <20060729201139.GA8574@localhost.localdomain>

Patch to audit return codes for kernel_thread.  This patch corrects callers who
have differing assumptions about the meaning of a zero return code.  I've
normalized all the callers to consider a zero return code a successful return.

Thanks & Regards
Neil
