From 95e2a3b3ef177730019e3799917193595133b275 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Jan=20H=2E=20Sch=C3=B6nherr?= Date: Sat, 16 Sep 2017 22:12:24 +0200 Subject: [PATCH] Revert "KVM: Don't accept obviously wrong gsi values via KVM_IRQFD" MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This reverts commit 36ae3c0a36b7456432fedce38ae2f7bd3e01a563. The commit broke compilation on !CONFIG_HAVE_KVM_IRQ_ROUTING. Also, there may be cases with CONFIG_HAVE_KVM_IRQ_ROUTING, where larger gsi values make sense. As the commit was meant as an early indicator to user space that something is wrong, reverting just restores the previous behavior where overly large values are ignored when encountered (without any direct feedback).
