From 274091c07482773c7e81cbe70f0b46b4606048d0 Mon Sep 17 00:00:00 2001 From: Etienne Dechamps Date: Thu, 27 Sep 2012 16:05:15 +0200 Subject: [PATCH] Fix VOP_CLOSE() in userspace. Currently, for unknown reasons, VOP_CLOSE() is a no-op in userspace. This causes file descriptor leaks. This is especially problematic with long ztest runs, since zpool.cache is opened repeatedly and never closed, resulting in resource exhaustion (EMFILE errors). This patch fixes the issue by making VOP_CLOSE() do what it is supposed to do.
