From f1688e0431d3a395388e70fe21da89ed0de0c323 Mon Sep 17 00:00:00 2001 From: Dave Reisner Date: Wed, 2 Jan 2013 08:54:37 -0500 Subject: [PATCH] debugfs: convert gid= argument from decimal, not octal This patch technically breaks userspace, but I suspect that anyone who actually used this flag would have encountered this brokenness, declared it lunacy, and already sent a patch.
