2010-03-03ALSA: riptide: clean up while loopDan Carpenter
If getpaths() returned an odd number this would be a buffer under-run and an endless loop. It turns out that getpaths() can only return even numbers, but let's make it easy for people auditing code. With the new code you don't need to look at getpaths(). This silences a smatch warning. Signed-off-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

We forget to release page references we acquire in ext4_da_block_invalidatepages.

2010-03-03mac80211: Fix HT rate control configurationSujith
Handling HT configuration changes involved setting the channel with the new HT parameters and then issuing a rate_update() notification to the driver. This behavior changed after the off-channel changes. Now, the channel is not updated with the new HT params in enable_ht() - instead, it is now done when the scan work terminates. This results in the driver depending on stale information, defaulting to non-HT mode always. Fix this by passing the new channel type to the driver.

2010-03-03x86, mrst: Fix APB timer per cpu clockeventJacob Pan
The current APB timer code incorrectly registers a static copy of the clockevent device for the boot CPU. The per cpu clockevent should be used instead. This bug was hidden by zero-initialized data; as such it did not get exposed in testing, but was discovered by code review.

2010-03-03init: Open /dev/console from rootfsEric W. Biederman
To avoid potential problems with an empty /dev open /dev/console from rootfs instead of waiting to mount our root filesystem and mounting it there. This effectively guarantees that there will be a device node, and it won't be on a filesystem that we will ever unmount, so there are no issues with leaving /dev/console open and pinning the filesystem. This is actually more effective than automatically mounting devtmpfs on /dev because it removes removes the occasionally problematic assumption that /dev/console exists from the boot code. With this patch I was able to throw busybox on my /boot partition (which has no /dev directory) and boot into userspace without problems. The only possible negative consequence I can think of is that someone out there deliberately used did not use a character device that is major 5 minor 2 for /dev/console. Does anyone know of a situation in which that could make sense? Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2010-03-03vfs: add NOFOLLOW flag to umount(2)Miklos Szeredi
Add a new UMOUNT_NOFOLLOW flag to umount(2). This is needed to prevent symlink attacks in unprivileged unmounts (fuse, samba, ncpfs). Additionally, return -EINVAL if an unknown flag is used (and specify an explicitly unused flag: UMOUNT_UNUSED). This makes it possible for the caller to determine if a flag is supported or not.

2010-03-03VFS: Clean up shared mount flag propagationValerie Aurora
The handling of mount flags in set_mnt_shared() got a little tangled up during previous cleanups, with the following problems: * MNT_PNODE_MASK is defined as a literal constant when it should be a bitwise xor of other MNT_* flags * set_mnt_shared() clears and then sets MNT_SHARED (part of MNT_PNODE_MASK) * MNT_PNODE_MASK could use a comment in mount.h * MNT_PNODE_MASK is a terrible name, change to MNT_SHARED_MASK This patch fixes these problems.
