2010-11-16suspend: constify platform_suspend_opsLionel Debroux
While at it, fix two checkpatch errors. Several non-const struct instances constified by this patch were added after the introduction of platform_suspend_ops in checkpatch.pl's list of "should be const" structs (79404849e90a41ea2109bd0e2f7c7164b0c4ce73). Patch against mainline. Inspired by hunks of the grsecurity patch, updated for newer kernels.

2010-11-16backlight: constify backlight_opsLionel Debroux
backlight_device_register has been expecting a const "ops" argument, and using it as such, since 9905a43b2d563e6f89e4c63c4278ada03f2ebb14. Let's make the remaining backlight_ops instances const.

2010-11-15Docs/Kconfig: Update: osdl.org -> linuxfoundation.orgMichael Witten
Some of the documentation refers to web pages under the domain `osdl.org'. However, `osdl.org' now redirects to `linuxfoundation.org'. Rather than rely on redirections, this patch updates the addresses appropriately; for the most part, only documentation that is meant to be current has been updated. The patch should be pretty quick to scan and check; each new web-page url was gotten by trying out the original URL in a browser and then simply copying the the redirected URL (formatting as necessary). There is some conflict as to which one of these domain names is preferred: linuxfoundation.org linux-foundation.org So, I wrote: info@linuxfoundation.org and got this reply: Message-ID: <4CE17EE6.9040807@linuxfoundation.org> Date: Mon, 15 Nov 2010 10:41:42 -0800 From: David Ames <david@linuxfoundation.org> ... linuxfoundation.org is preferred. The canonical name for our web site is www.linuxfoundation.org. Our list site is actually lists.linux-foundation.org. Regarding email linuxfoundation.org is preferred there are a few people who choose to use linux-foundation.org for their own reasons. Consequently, I used `linuxfoundation.org' for web pages and `lists.linux-foundation.org' for mailing-list web pages and email addresses; the only personal email address I updated from `@osdl.org' was that of Andrew Morton, who prefers `linux-foundation.org' according `git log'.

2010-10-30fs-writeback.c: unify some common codeLinus Torvalds
The btrfs merge looks like hell, because it changes fs-writeback.c, and the crazy code has this repeated "estimate number of dirty pages" counting that involves three different helper functions. And it's done in two different places. Just unify that whole calculation as a "get_nr_dirty_pages()" helper function, and the merge result will look half-way decent.

2010-10-30audit: Call tty_audit_push_task() outside preempt disabledThomas Gleixner
While auditing all tasklist_lock read_lock sites I stumbled over the following call chain: audit_prepare_user_tty() read_lock(&tasklist_lock); tty_audit_push_task(); mutex_lock(&buf->mutex); --> buf->mutex is locked with preemption disabled. Solve this by acquiring a reference to the task struct under rcu_read_lock and call tty_audit_push_task outside of the preempt disabled region. Move all code which needs to be protected by sighand lock into tty_audit_push_task() and use lock/unlock_sighand as we do not hold tasklist_lock.

In commit 2a48fc0ab24241755dc93bfd4f01d68efab47f5a ('block: autoconvert trivial BKL users to private mutex'), Arnd replaced the BKL usage with a mutex. However, Maxim has already provided a better fix in commit 480792b7bf188c29b8d4b10fee65c3a06ec5dbf7 ('mtd: blktrans: kill BKL'), which was simply to remove the BKL without replacing it — since he'd already made it do all necessary locking for itself.

2010-10-29Btrfs: allow subvol deletion by unprivileged user with -o user_subvol_rm_allowedSage Weil
Add a mount option user_subvol_rm_allowed that allows users to delete a (potentially non-empty!) subvol when they would otherwise we allowed to do an rmdir(2). We duplicate the may_delete() checks from the core VFS code to implement identical security checks (minus the directory size check).
