Subject: Re: [PATCH 2/10] splice
Date: Sun, 22 Jul 2012 18:17:31 -0700 [thread overview]
Message-ID: <20120722181731.051d67d5@newbook> (raw)
In-Reply-To: <20120722181332.191d4fa5@newbook>
[-- Attachment #1: Type: text/plain, Size: 178 bytes --]
This adds a syscall wrapper for splice.
I trusted git apply too much, so there are two parts to this patch:
one to add the syscall, one to fix the header back up...
