From 9ae3974714d6d26711cfe59ed7bf5559c43a472b Mon Sep 17 00:00:00 2001 From: Ben Kaduk Date: Sun, 19 Dec 2010 19:33:28 -0500 Subject: [PATCH] FBSD7: Don't sleep with the glock On FreeBSD 7.X, vinvalbuf() can (will) sleep; this results in a panic when the kernel is configured with WITNESS and we hold the glock around it. Drop the glock in this case.
