* Atmel MXT touchscreen: increase reset timeoutsLinus Torvalds2013-03-09
| | | | | | | | | | | | | There is a more complete atmel patch-series out by Nick Dyer that fixes this and other things, but in the meantime this is the minimal thing to get the touchscreen going on (at least my) Pixel Chromebook. Not that I want my dirty fingers near that beautiful screen, but it seems that a non-initialized touchscreen will also end up being a constant wakeup source, so you have to disable it to go to sleep. And it's easier to just fix the initialization sequence. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

| * Btrfs: improve the delayed inode throttlingChris Mason2013-03-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The delayed inode code batches up changes to the btree in hopes of doing them in bulk. As the changes build up, processes kick off worker threads and wait for them to make progress. The current code kicks off an async work queue item for each delayed node, which creates a lot of churn. It also uses a fixed 1 HZ waiting period for the throttle, which allows us to build a lot of pending work and can slow down the commit. This changes us to watch a sequence counter as it is bumped during the operations. We kick off fewer work items and have each work item do more work.

| * Btrfs: fix a mismerge in btrfs_balance()Ilya Dryomov2013-03-06
| | | | | | | | | | | | | | | | | | | | | | Raid56 merge (merge commit e942f88) had mistakenly removed a call to __cancel_balance(), which resulted in balance not cleaning up after itself after a successful finish. (Cleanup includes switching the state, removing the balance item and releasing mut_ex_op testnset lock.) Bring it back.

| | * Btrfs: allow running defrag in parallel to administrative tasksStefan Behrens2013-03-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 5ac00add added a testnset mutex and code that disallows running administrative tasks in parallel. It is prevented that the device add/delete/balance/replace/resize operations are started in parallel. By mistake, the defragmentation operation was included in the check for mutually exclusiveness as well. This is fixed with this commit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We first use btrfs_std_error hook to replace with BUG_ON, and we also need to cleanup what is left, including reloc roots rbtree and reloc roots list. Here we use a helper function to cleanup both rbtree and list, and since this function can also be used in the balance recover path, we also make the change as well to keep code simple.

At the end of the transaction commitment, the transaction handler was freed, so we should not access it after the transaction commitment. - we were not aware of the error which happened during the snapshot creation if we submitted a async transaction commitment. - pending snapshot access vs pending snapshot free. when something wrong happened after we submitted a async transaction commitment, the transaction committer would cleanup the pending snapshots and free them. But the snapshot creators were not aware of it, they would access the freed pending snapshots. This patch fixes the above problems by: - remove the dangerous code that accessed the freed handler - assign ->error if the error happens during the snapshot creation - the transaction committer doesn't free the pending snapshots, just assigns the error number and evicts them before we unblock the transaction.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to inc the nlink of deleted entries when running replay so we can do the unlink on the fs_root and get everything cleaned up and then have the orphan cleanup do the right thing. The problem is inc_nlink complains about this, even thought it still does the right thing. So use set_nlink() if our i_nlink is 0 to keep users from seeing the warnings during log replay.

| * | Btrfs: enforce min_bytes parameter during extent allocationChris Mason2013-03-05
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 24542bf7ea5e4fdfdb5157ff544c093fa4dcb536 changed preallocation of extents to cap the max size we try to allocate. It's a valid change, but the extent reservation code is also used by balance, and that can't tolerate a smaller extent being allocated. __btrfs_prealloc_file_range already has a min_size parameter, which is used by relocation to request a specific extent size. This commit adds an extra check to enforce that minimum extent size. Signed-off-by: Chris Mason <chris.mason@fusionio.com> Reported-by: Stefan Behrens <sbehrens@giantdisaster.de>

Platform data may specify a device is a touchpad using the is_tp flag. This will cause the driver to perform some touchpad specific initializations, such as: * register input device name "Atmel maXTouch Touchpad" instead of Touchscreen. * register BTN_LEFT & BTN_TOOL_* event types. * register axis resolution (as a fixed constant, for now) * register BUTTONPAD property * process GPIO buttons using reportid T19 Input event GPIO mapping is done by the platform data key_map array. key_map[x] should contain the KEY or BTN code to send when processing GPIOx from T19.

Unfortunately, it releases the page before trying to unlock it. At that point, the page might be gone by the time the unlock comes in. Unlock the page first before checking the value of "rc", and only then end writeback and release the pages. The page lock isn't required for any of those operations so this should be safe.

The weird behavior has been changed such that negative IDs are treated as invalid. As the behavior change was subtle, WARN_ON_ONCE() was added in the hope of determining who's calling idr functions with negative IDs so that they can be examined for problems. Up until now, all two reported cases are ID number coming directly from userland and getting fed into idr_find() and the warnings seem to cause more problems than being helpful.

Since compat syscall arguments are always sign-extended on tile, this means that a seek value of 0xffffffff will be incorrectly interpreted as a value of -1ULL. To avoid the risk of breaking binary compatibility on architectures that already use sys_llseek this way, we follow the same path as MIPS and provide a wrapper override.
