Yannick found that video does not work with 2.6.34. The cause of this bug was that the BIOS had assigned the wrong range to the PCI bridge above the video device. Before 2.6.34 the kernel would have shrunk the size of the bridge window, but since d65245c3 PCI: don't shrink bridge resources the kernel will avoid shrinking BIOS ranges. So zero out the old range if we fail to claim it at boot time; this will cause us to allocate a new range at startup, restoring the 2.6.34 behavior. Fixes regression https://bugzilla.kernel.org/show_bug.cgi?id=16009 . Reported-by:

There are devices out there which are PCI Hot-plug controllers with compaq PCI IDs, but are not bridges, hence have pdev->subordinate NULL. But cpqphp expects the pointer to be non-NULL. Add a check to the probe function to avoid oopses like: BUG: unable to handle kernel NULL pointer dereference at 00000050 IP: [<f82e3c41>] cpqhpc_probe+0x951/0x1120 [cpqphp] *pdpt = 0000000033779001 *pde = 0000000000000000 ... The device here was: 00:0b.0 PCI Hot-plug controller [0804]: Compaq Computer Corporation PCI Hotplug Controller [0e11:a0f7] (rev 11) Subsystem: Compaq Computer Corporation Device [0e11:a2f8] Signed-off-by:

We can often deal with PCI resource issues by moving devices around. In that case, there's no point in alarming the user with messages like these. There are many bug reports where the message itself is the only problem, e.g., https://bugs.launchpad.net/ubuntu/+source/linux/+bug/413419 . Signed-off-by:

The "file" argument for fsync is never null so we can remove this check. What drew my attention here is that 7ea80859 : "drop unused dentry argument to ->fsync" introduced an unconditional dereference at the start of the function and that generated a smatch warning. Signed-off-by:

If btrfs_ioctl_snap_destroy() deletes a snapshot but finishes with end_transaction(), the cleaner kthread may come in and drop the root in the same transaction. If that's the case, the root's refs still == 1 in the tree when btrfs_del_root() deletes the item, because commit_fs_roots() hasn't updated it yet (that happens during the commit). This wasn't a problem before only because btrfs_ioctl_snap_destroy() would commit the transaction before dropping the dentry reference, so the dead root wouldn't get queued up until after the fs root item was updated in the btree. Since it is not an error to drop the root reference and the root in the same transaction, just drop the BUG_ON() in btrfs_del_root(). Signed-off-by:

when used Posix File System Test Suite(pjd-fstest) to test btrfs, some cases about setfacl failed when noacl mount option used. I simplified used commands in pjd-fstest, and the following steps can reproduce it. ------------------------ # cd btrfs-part/ # mkdir aaa # setfacl -m m::rw aaa <- successed, but not expected by pjd-fstest. ------------------------ I checked ext3, a warning message occured, like as: setfacl: aaa/: Operation not supported Certainly, it's expected by pjd-fstest. So, i compared acl.c of btrfs and ext3. Based on that, a patch created. Fortunately, it works. Signed-off-by:

On btrfs, do the following ------------------ # su user1 # cd btrfs-part/ # touch aaa # getfacl aaa # file: aaa # owner: user1 # group: user1 user::rw- group::rw- other::r-- # su user2 # cd btrfs-part/ # setfacl -m u::rwx aaa # getfacl aaa # file: aaa # owner: user1 # group: user1 user::rwx <- successed to setfacl group::rw- other::r-- ------------------ but we should prohibit it that user2 changing user1's acl. In fact, on ext3 and other fs, a message occurs: setfacl: aaa: Operation not permitted This patch fixed it. Signed-off-by:
