Message-Id: <1249564170-18627-1-git-send-email-arnd@arndb.de> Date: Thu, 6 Aug 2009 15:09:25 +0200 From: Arnd Bergmann <arnd@...db.de> To: linux-kernel@...r.kernel.org Cc: Christoph Hellwig <hch@....de>, Andi Kleen <andi@...stfloor.org>, Alexander Viro <viro@...iv.linux.org.uk>, Arnd Bergmann <arnd@...db.de> Subject: [PATCH 0/5] Kill the BKL in compat ioctl handling I noticed that compat_sys_ioctl still holds the big kernel lock for all ioctl conversion handlers. It would be easy to push this one level down and only do it where necessary, but I decided to clean it up some more at the same time and move all the VT ioctl handling into the specific drivers.
