2012-07-23Btrfs: add DEVICE_READY ioctlJosef Bacik
This will be used in conjunction with btrfs device ready <dev>. This is needed for initrd's to have a nice and lightweight way to tell if all of the devices needed for a file system are in the cache currently. This keeps them from having to do mount+sleep loops waiting for devices to show up. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>

The last and final kernel user, ICMP address replies, has been removed. Signed-off-by: David S. Miller <davem@davemloft.net>
2012-07-23ipv4: Really ignore ICMP address requests/replies.David S. Miller
Alexey removed kernel side support for requests, and the only thing we do for replies is log a message if something doesn't look right. As Alexey's comment indicates, this belongs in userspace (if anywhere), and thus we can safely just get rid of this code. Signed-off-by: David S. Miller <davem@davemloft.net>

2012-07-23I2C: MV64XYZ: Add Device Tree supportAndrew Lunn
Extends the driver to get properties from device tree. Rather than pass the N & M factors in DT, use the more standard clock-frequency property. Calculate N & M at run time. In order to do this, we need to know tclk. So the driver uses clk_get() etc in order to get the clock and clk_get_rate() to determine the tclk rate. Not all platforms however have CLK, so some #ifdefery is needed to ensure the driver still compiles when CLK is not available.

2012-07-23locks: fix checking of fcntl_setlease argumentJ. Bruce Fields
The only checks of the long argument passed to fcntl(fd,F_SETLEASE,.) are done after converting the long to an int. Thus some illegal values may be let through and cause problems in later code. [ They actually *don't* cause problems in mainline, as of Dave Jones's commit 8d657eb3b438 "Remove easily user-triggerable BUG from generic_setlease", but we should fix this anyway. And this patch will be necessary to fix real bugs on earlier kernels. ] Cc: stable@vger.kernel.org Signed-off-by: J.

2012-07-23Btrfs: flush delayed inodes if we're short on spaceJosef Bacik
Those crazy gentoo guys have been complaining about ENOSPC errors on their portage volumes. This is because doing things like untar tends to create lots of new files which will soak up all the reservation space in the delayed inodes. Usually this gets papered over by the fact that we will try and commit the transaction, however if this happens in the wrong spot or we choose not to commit the transaction you will be screwed. So add the ability to expclitly flush delayed inodes to free up space. Please test this out guys to make sure it works since as usual I cannot reproduce.

2012-07-23btrfs: join DEV_STATS ioctls to oneDavid Sterba
Commit c11d2c236cc260b36 (Btrfs: add ioctl to get and reset the device stats) introduced two ioctls doing almost the same thing distinguished by just the ioctl number which encodes "do reset after read". I have suggested http://www.mail-archive.com/linux-btrfs@vger.kernel.org/msg16604.html to implement it via the ioctl args. This hasn't happen, and I think we should use a more clean way to pass flags and should not waste ioctl numbers.

rebased Rebased on btrfs-next and retested. Inform should_defrag_range if BTRFS_DEFRAG_RANGE_COMPRESS is set.

2012-07-23Btrfs: don't update atime on RO subvolumesAlexander Block
Before the update_time inode operation was indroduced, it was not possible to prevent updates of atime on RO subvolumes. VFS was only able to check for RO on the mount, but did not know anything about btrfs subvolumes. btrfs_update_time does now check if the root is RO and skip updating of times.

2012-07-23Btrfs: allow mount -o remount,compress=noArnd Hannemann
Btrfs allows to turn on compression on a mounted and used filesystem by issuing mount -o remount,compress=lzo. This patch allows to turn compression off again while the filesystem is mounted. As suggested by David Sterba if the compress-force option was set, it is implicitly cleared if compression is turned off.

2012-07-23Merge branch 'for-linus-2' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs Pull the big VFS changes from Al Viro: "This one is *big* and changes quite a few things around VFS. What's in there: - the first of two really major architecture changes - death to open intents. The former is finally there; it was very long in making, but with Miklos getting through really hard and messy final push in fs/namei.c, we finally have it. Unlike his variant, this one doesn't introduce struct opendata; what we have instead is ->atomic_open() taking preallocated struct file * and passing everything via its fields. Instead of returning struct file *, it returns -E... on error, 0 on success and 1 in "deal with it yourself" case (e.g. symlink found on server, etc.). See comments before fs/namei.c:atomic_open(). That made a lot of goodies finally possible and quite a few are in that pile: ->lookup(), ->d_revalidate() and ->create() do not get struct nameidata * anymore; ->lookup() and ->d_revalidate() get lookup flags instead, ->create() gets "do we want it exclusive" flag. With the introduction of new helper (kern_path_locked()) we are rid of all struct nameidata instances outside of fs/namei.c; it's still visible in namei.h, but not for long. Come the next cycle, declaration will move either to fs/internal.h or to fs/namei.c itself. [me, miklos, hch] - The second major change: behaviour of final fput(). Now we have __fput() done without any locks held by caller *and* not from deep in call stack. That obviously lifts a lot of constraints on the locking in there. Moreover, it's legal now to call fput() from atomic contexts (which has immediately simplified life for aio.c). We also don't need anti-recursion logics in __scm_destroy() anymore. There is a price, though - the damn thing has become partially asynchronous. For fput() from normal process we are guaranteed that pending __fput() will be done before the caller returns to userland, exits or gets stopped for ptrace. For kernel threads and atomic contexts it's done via schedule_work(), so theoretically we might need a way to make sure it's finished; so far only one such place had been found, but there might be more. There's flush_delayed_fput() (do all pending __fput()) and there's __fput_sync() (fput() analog doing __fput() immediately). I hope we won't need them often; see warnings in fs/file_table.c for details. [me, based on task_work series from Oleg merged last cycle] - sync series from Jan - large part of "death to sync_supers()" work from Artem; the only bits missing here are exofs and ext4 ones. As far as I understand, those are going via the exofs and ext4 trees resp.; once they are in, we can put ->write_super() to the rest, along with the thread calling it. - preparatory bits from unionmount series (from dhowells). - assorted cleanups and fixes all over the place, as usual. This is not the last pile for this cycle; there's at least jlayton's ESTALE work and fsfreeze series (the latter - in dire need of fixes, so I'm not sure it'll make the cut this cycle). I'll probably throw symlink/hardlink restrictions stuff from Kees into the next pile, too. Plus there's a lot of misc patches I hadn't thrown into that one - it's large enough as it is..." * 'for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (127 commits) ext4: switch EXT4_IOC_RESIZE_FS to mnt_want_write_file() btrfs: switch btrfs_ioctl_balance() to mnt_want_write_file() switch dentry_open() to struct path, make it grab references itself spufs: shift dget/mntget towards dentry_open() zoran: don't bother with struct file * in zoran_map ecryptfs: don't reinvent the wheels, please - use struct completion don't expose I_NEW inodes via dentry->d_inode tidy up namei.c a bit unobfuscate follow_up() a bit ext3: pass custom EOF to generic_file_llseek_size() ext4: use core vfs llseek code for dir seeks vfs: allow custom EOF in generic_file_llseek code vfs: Avoid unnecessary WB_SYNC_NONE writeback during sys_sync and reorder sync passes vfs: Remove unnecessary flushing of block devices vfs: Make sys_sync writeout also block device inodes vfs: Create function for iterating over block devices vfs: Reorder operations during sys_sync quota: Move quota syncing to ->sync_fs method quota: Split dquot_quota_sync() to writeback and cache flushing part vfs: Move noop_backing_dev_info check from sync into writeback ...

2012-07-23MIPS: JZ4740: reset: Initialize hibernate wakeup counters.Maarten ter Huurne
In hibernation mode only the wakeup logic and the RTC are left running, so this is what users perceive as power down. If the counters are not initialized, the corresponding pin (typically connected to the power button) has to be asserted for two seconds before the device wakes up. Most users expect a shorter wakeup time. I took the timing values of 100 ms and 60 ms from BouKiCHi's patch for the Dingoo A320 kernel.

2012-07-23MIPS: Prune some target specific code out of prom.cDavid Daney
This code is not common enough to be in a shared file. It is also not used by any existing boards, so just remove it. [ralf@linux-mips.org: Dropped removal of irq_create_of_mapping which was already removed by abd2363f6a5f1030b935e0bdc15cf917313b3b10 [irq_domain/mips: Allow irq_domain on MIPS]. Moved device_tree_init() and dependencies to its sole user, the XLP code.] Signed-off-by: David Daney <david.daney@cavium.com> Cc: linux-mips@linux-mips.org Cc: devicetree-discuss@lists.ozlabs.org Cc: grant.likely@secretlab.ca Cc: linux-kernel@vger.kernel.org Patchwork: https://patchwork.linux-mips.org/patch/2946/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
