Re: [KJ] (re) audit return code handling for kernel_thread [3/3]

[Neil Horman]

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
