Subject: [patch 02/10] Dont touch fs_struct in usermodehelper
Date: Tue, 09 Oct 2007 20:05:05 +0200 [thread overview]
Message-ID: <20071009180512.277617567@X40.localnet> (raw)
In-Reply-To: 20071009180503.075306583@X40.localnet
[-- Attachment #1: vfs/dont-touch-current-fs-usermodehelper.diff --]
[-- Type: text/plain, Size: 843 bytes --]
This test seems to be unnecessary since we always have rootfs mounted before
calling a usermodehelper.
