From 98232d504db0a1f91ecaa93686ed3bf61963103b Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Thu, 4 May 2006 09:13:49 +0200 Subject: [PATCH] [PATCH] compat_sys_vmsplice: one-off in UIO_MAXIOV check nr_segs may not be > UIO_MAXIOV, however it may be equal to. This makes the behaviour identical to the real sys_vmsplice(). The other foov syscalls also agree that this is the way to go.
