This patch adds ioctls to vfs for compatibility with legacy XFS pre-allocation ioctls (XFS_IOC_*RESVP*). The implementation effectively invokes sys_fallocate for the new ioctls. Also handles the compat_ioctl case. Note: These legacy ioctls are also implemented by OCFS2.

After the recent changes that went into mm/vmscan.c to overhaul stuff, we ended up with these warnings on no-mmu systems: mm/vmscan.c: In function `shrink_page_list': mm/vmscan.c:580: warning: unused variable `vm_flags' mm/vmscan.c: In function `shrink_active_list': mm/vmscan.c:1294: warning: `vm_flags' may be used uninitialized in this function mm/vmscan.c:1242: note: `vm_flags' was declared here This is because the no-mmu function defines page_referenced() to work on the first argument only (the page). It does not clear the vm_flags given to it because for no-mmu systems, they never actually get utilized. Since that is no longer strictly true, we need to set vm_flags to 0 like everyone else so gcc can do proper dead code elimination without annoying us with unused warnings.

If a kthread happens to use get_user_pages() on an mm (as KSM does), there's a chance that it will end up trying to read in a swap page, then oops in grab_swap_token() because the kthread has no mm: GUP passes down the right mm, so grab_swap_token() ought to be using it. We have not identified a stronger case than KSM's daemon (not yet in mainline), but the issue must have come up before, since RHEL has included a fix for this for years (though a different fix, they just back out of grab_swap_token if current->mm is unset: which is what we first proposed, but using the right mm here seems more correct).

Most hardware has limits on minimum and maximum image dimensions and also requirements about alignment. For example, image width must be even or a multiple of four. Some hardware has requirements that the total image size (width * height) be a multiple of some power of two. v4l_bound_align_image() will enforce min and max width and height, power of two alignment on width and height, and power of two alignment on total image size. It uses an efficient algorithm that will try to find the "closest" image size that meets the requirements.

Add a new s_config core ops call: this is called with the irq and platform data to be used to initialize the subdev. Added new v4l2_i2c_new_subdev_cfg and v4l2_i2c_new_subdev_board calls that allows you to pass these new arguments. The existing v4l2_i2c_new_subdev functions were modified to also call s_config. In the future the existing v4l2_i2c_new_subdev functions will be replaced by a single v4l2_i2c_new_subdev function similar to v4l2_i2c_new_subdev_cfg but without the irq and platform_data arguments.

The purpose of this patch is to improve the remote mount path lookup support for distributed filesystems such as the NFSv4 client. When given a mount command of the form "mount server:/foo/bar /mnt", the NFSv4 client is required to look up the filehandle for "server:/", and then look up each component of the remote mount path "foo/bar" in order to find the directory that is actually going to be mounted on /mnt. Following that remote mount path may involve following symlinks, crossing server-side mount points and even following referrals to filesystem volumes on other servers. Since the standard VFS path lookup code already supports walking paths that contain all these features (using in-kernel automounts for following referrals) we would like to be able to reuse that rather than duplicate the full path traversal functionality in the NFSv4 client code. This patch therefore defines a VFS helper function create_mnt_ns(), that sets up a temporary filesystem namespace and attaches a root filesystem to it. It exports the create_mnt_ns() and put_mnt_ns() function for use by filesystem modules.

SLAB uses get/put_online_cpus() which use a mutex which is itself only initialized when cpu_hotplug_init() is called. Currently we hang suring boot in SLAB due to doing that too late. Reported by James Bottomley and Sachin Sant (and possibly others). Debugged by Benjamin Herrenschmidt. This just removes the dynamic initialization of the data structures, and replaces it with a static one, avoiding this dependency entirely, and removing one unnecessary special initcall.

Currently it supports: bit LSB 0 = general libfc debugging 1 = lport debugging 2 = disc debugging 3 = rport debugging 4 = fcp debugging 5 = EM debugging 6 = exch/seq debugging 7 = scsi logging (mostly error handling) the other bits are not used at this time.

This information allows userspace to implement a hybrid policy where it can store the rfkill soft-blocked state in platform non-volatile storage if available, and if not then file-based storage can be used. Some users prefer platform non-volatile storage because of the behaviour when dual-booting multiple versions of Linux, or if the rfkill setting is changed in the BIOS setting screens, or if the BIOS responds to wireless-toggle hotkeys itself before the relevant platform driver has been loaded.

The setting of the "persistent" flag is also made more explicit using a new rfkill_init_sw_state() function, instead of special-casing rfkill_set_sw_state() when it is called before registration. Suspend is a bit of a corner case so we try to get away without adding another hack to rfkill-input - it's going to be removed soon. If the state does change over suspend, users will simply have to prod rfkill-input twice in order to toggle the state. Userspace policy agents will be able to implement a more consistent user experience. For example, they can avoid the above problem if they toggle devices individually. Then there would be no "global state" to get out of sync. Currently there are only two rfkill drivers with persistent soft-blocked state. thinkpad-acpi already checks the software state on resume. eeepc-laptop will require modification.

For video4linux we sometimes need to probe for a single i2c address. Normally you would do it like this: static const unsigned short addrs[] = { addr, I2C_CLIENT_END }; client = i2c_new_probed_device(adapter, &info, addrs); This is a bit awkward and I came up with this macro: #define V4L2_I2C_ADDRS(addr, addrs...) \ ((const unsigned short []){ addr, ## addrs, I2C_CLIENT_END }) This can construct a list of one or more i2c addresses on the fly. But this is something that really belongs in i2c.h, renamed to I2C_ADDRS. With this macro we can just do: client = i2c_new_probed_device(adapter, &info, I2C_ADDRS(addr)); Note that this can also be used to initialize an array: static const unsigned short addrs[] = I2C_ADDRS(0x2a, 0x2c); Whether you want to is another matter, but it works. This functionality is also available in the oldest supported gcc (3.2). Signed-off-by: NHans Verkuil <hverkuil@xs4all.nl> Signed-off-by: NJean Delvare <khali@linux-fr.org>

Add a sysfs interface to instantiate and delete I2C devices. This is primarily a replacement of the force_* module parameters implemented by some i2c drivers. These module parameters were implemented internally by the I2C_CLIENT_INSMOD* macros, which don't scale well. This can also be used when developing a driver on a self-soldered board which doesn't yet have proper I2C device declaration at the platform level, and presumably for various debugging situations.
