e681c04 Lukas Czerner 20 November 2010, 02:47:07 UTC ext4: Add EXT4_IOC_TRIM ioctl to handle batched discard Filesystem independent ioctl was rejected as not common enough to be in core vfs ioctl. Since we still need to access to this functionality this commit adds ext4 specific ioctl EXT4_IOC_TRIM to dispatch ext4_trim_fs(). It takes fstrim_range structure as an argument. fstrim_range is definec in the include/linux/fs.h and its definition is as follows. struct fstrim_range { __u64 start; __u64 len; __u64 minlen; } start - first Byte to trim len - number of Bytes to trim from start minlen - minimum extent length to trim, free extents shorter than this number of Bytes will be ignored. This will be rounded up to fs block size. After the FITRIM is done, the number of actually discarded Bytes is stored in fstrim_range.len to give the user better insight on how much storage space has been really released for wear-leveling.

93bb41f Lukas Czerner 20 November 2010, 02:18:35 UTC fs: Do not dispatch FITRIM through separate super_operation There was concern that FITRIM ioctl is not common enough to be included in core vfs ioctl, as Christoph Hellwig pointed out there's no real point in dispatching this out to a separate vector instead of just through ->ioctl. So this commit removes ioctl_fstrim() from vfs ioctl and trim_fs from super_operation structure.

33e0d57 Linus Torvalds 19 November 2010, 19:54:40 UTC Revert "kernel: make /proc/kallsyms mode 400 to reduce ease of attacking" This reverts commit 59365d136d205cc20fe666ca7f89b1c5001b0d5a. It turns out that this can break certain existing user land setups. Quoth Sarah Sharp: "On Wednesday, I updated my branch to commit 460781b from linus' tree, and my box would not boot. klogd segfaulted, which stalled the whole system. At first I thought it actually hung the box, but it continued booting after 5 minutes, and I was able to log in. It dropped back to the text console instead of the graphical bootup display for that period of time. dmesg surprisingly still works. I've bisected the problem down to this commit (commit 59365d136d205cc20fe666ca7f89b1c5001b0d5a) The box is running klogd 1.5.5ubuntu3 (from Jaunty). Yes, I know that's old. I read the bit in the commit about changing the permissions of kallsyms after boot, but if I can't boot that doesn't help." So let's just keep the old default, and encourage distributions to do the "chmod -r /proc/kallsyms" in their bootup scripts. This is not worth a kernel option to change default behavior, since it's so easily done in user space.

5a9ae68 Darrick J. Wong 19 November 2010, 14:56:44 UTC ext4: ext4_fill_super shouldn't return 0 on corruption At the start of ext4_fill_super, ret is set to -EINVAL, and any failure path out of that function returns ret. However, the generic_check_addressable clause sets ret = 0 (if it passes), which means that a subsequent failure (e.g. a group checksum error) returns 0 even though the mount should fail. This causes vfs_kern_mount in turn to think that the mount succeeded, leading to an oops. A simple fix is to avoid using ret for the generic_check_addressable check, which was last changed in commit 30ca22c70e3ef0a96ff84de69cd7e8561b416cb2. Signed-off-by: Darrick J.

e7dbb2f Keith Packard 16 November 2010, 08:03:53 UTC drm/i915: Take advantage of auto-polling CRT hotplug detection on PCH hardware Both IBX and CPT have an automatic hotplug detection mode which appears to work reliably enough that we can dispense with the manual force hotplug trigger stuff. This means that hotplug detection is as simple as reading the current hotplug register values. The first time the hotplug detection is activated, the code synchronously waits for a hotplug sequence in case the hardware hasn't bothered to do a detection cycle since being initialized.

51311d0 Chris Wilson 17 November 2010, 09:10:42 UTC drm/i915: Do not hold mutex when faulting in user addresses Linus Torvalds found that it was rather trivial to trigger a system freeze: In fact, with lockdep, I don't even need to do the sysrq-d thing: it shows the bug as it happens. It's the X server taking the same lock recursively. Here's the problem: ============================================= [ INFO: possible recursive locking detected ] 2.6.37-rc2-00012-gbdbd01a #7 --------------------------------------------- Xorg/2816 is trying to acquire lock: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c626c>] i915_gem_fault+0x50/0x17e but task is already holding lock: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a other info that might help us debug this: 2 locks held by Xorg/2816: #0: (&dev->struct_mutex){+.+.+.}, at: [<ffffffff812c403b>] i915_mutex_lock_interruptible+0x28/0x4a #1: (&mm->mmap_sem){++++++}, at: [<ffffffff81022d4f>] page_fault+0x156/0x37b This recursion was introduced by rearranging the locking to avoid the double locking on the fast path (4f27b5d and fbd5a26d) and the introduction of the prefault to encourage the fast paths (b5e4f2b). In order to undo the problem, we rearrange the code to perform the access validation upfront, attempt to prefault and then fight for control of the mutex. the best case scenario where the mutex is uncontended the prefaulting is not wasted.

For example ixgbe does this as features and offloads are toggled. Presumably this could also happen across down/up on most devices if the available resources changed (cpu offlined).

1c2c25c Michael Neuling 17 November 2010, 16:32:59 UTC powerpc: Fix call to subpage_protection() In: powerpc/mm: Fix pgtable cache cleanup with CONFIG_PPC_SUBPAGE_PROT commit d28513bc7f675d28b479db666d572e078ecf182d Author: David Gibson <david@gibson.dropbear.id.au> subpage_protection() was changed to to take an mm rather a pgdir but it didn't change calling site in hashpage_preload().
