From 6e12ea4658487ba9c746e95b31014cb89f63703b Mon Sep 17 00:00:00 2001 From: Andi Kleen Date: Tue, 1 Jun 2010 23:04:40 +0200 Subject: [PATCH] USB-BKL: Remove lock_kernel in usbfs update_sb() 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.
