From 073c21416268658bd1bc573af85eeac2ebb56ed5 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 21 Oct 2010 15:53:15 +0200 Subject: BKL: remove BKL from qnx4 All uses of the BKL in qnx4 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.
