Message-Id: <1275426285-9088-2-git-send-email-arnd@arndb.de> Date: Tue, 1 Jun 2010 23:04:40 +0200 From: Arnd Bergmann <arnd@...db.de> To: Greg KH <gregkh@...e.de> Cc: linux-kernel@...r.kernel.org, Arnd Bergmann <arnd@...db.de>, linux-usb@...r.kernel.org, Frederic Weisbecker <fweisbec@...il.com>, John Kacur <jkacur@...hat.com>, Andi Kleen <andi@...stfloor.org>, Andi Kleen <ak@...ux.intel.com> Subject: [PATCH 1/6] USB-BKL: Remove lock_kernel in usbfs update_sb() From: Andi Kleen <ak@...ux.intel.com> The code this is attempting to lock against does not use the BKL, so it's not needed. Most likely this code is still broken/racy (Al Viro also thinks so), but removing the BKL should not make it worse than before.
