Date: Thu, 3 Jun 2010 02:13:14 +0200 From: Arnd Bergmann <arnd@...db.de> To: linux-kernel@...r.kernel.org Cc: Arnd Bergmann <arnd@...db.de>, linux-usb@...r.kernel.org, Frederic Weisbecker <fweisbec@...il.com>, John Kacur <jkacur@...hat.com>, Ingo Molnar <mingo@...e.hu>, Jan Blunck <jblunck@...e.de> Subject: [RFC 0/5] BKL removal leftovers If we can complete the ioctl-pushdown, tty, block, vfs, usb, and v4l patch series for the next merge window, this is essentially what remains. As Ingo suggested, I've found a way to script the conversion from BKL to a per-file mutex that works for most of the remaining users, but I still manually needed to create a list of these, because there are some that are at best non-obvious. The question is how to merge that first patch without patch-bombing lkml with 100 trivial patches. For now, I've kept it as a single patch. The other patches are fairly straightforward. Among the code that still depends on CONFIG_BKL after this are a lot of file systems, DRM, fs/locks.c, USB-HID, i4l, v4l, dvb, oss and some old networking protocols. It's mostly code that I can live without on all of my machines, but not to the point that I'd expect distro kernels to ship without all of that. Arnd Bergmann (5): BKL: autoconvert trivial users to private mutex BKL: remove the BKL from kernel init code BKL: do not take BKL in do_coredump BKL: use no BKL in llseek BKL: introduce CONFIG_BKL. arch/cris/arch-v10/drivers/eeprom.c | 2 -
