From 6d7bccc2215c37205ede6c9cf84db64e7c4f9443 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 21 Oct 2010 15:58:01 +0200 Subject: BKL: remove BKL from freevxfs All uses of the BKL in freevxfs were the result of a pushdown into code that doesn't really need it. As Christoph points out, this is a read-only file system, which eliminates most of the races in readdir/lookup.
