| * block: only force kblockd unplugging from the schedule() pathJens Axboe2011-04-151-2/+2
| | | | | | | | | | | | | | | | | | For the explicit unplugging, we'd prefer to kick things off immediately and not pay the penalty of the latency to switch to kblockd. So let blk_finish_plug() do the run inline, while the implicit-on-schedule-out unplug will punt to kblockd. Signed-off-by: Jens Axboe <jaxboe@fusionio.com>
| * block: cleanup the block plug helper functionsChristoph Hellwig2011-04-151-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | It's a bit of a mess currently. task->plug is being cleared and reset in __blk_finish_plug(), and blk_finish_plug() is testing for a NULL plug which cannot happen even from schedule() anymore since it uses blk_needs_flush_plug() to determine whether to call into this function at all. So get rid of some of the cruft. Signed-off-by: Jens Axboe <jaxboe@fusionio.com>

* | brk: COMPAT_BRK: fix detection of randomized brkJiri Kosina2011-04-151-0/+3

It turns out that the way to detect whether brk has actually been randomized in the end or not introduced by that patch still doesn't work for those binaries, as reported by Geert: : /sbin/init from my old m68k ramdisk exists prematurely. : : Before the patch: : : | brk(0x80005c8e) = 0x80006000 : : After the patch: : : | brk(0x80005c8e) = 0x80005c8e : : Old libc5 considers brk() to have failed if the return value is not : identical to the requested value. I don't like it, but currently see no better option than a bit flag in task_struct to catch the CONFIG_COMPAT_BRK && randomize_va_space == 2 case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Xen save/restore is going to use hibernate device callbacks for quiescing devices and putting them back to normal operations and it would need to select CONFIG_HIBERNATION for this purpose. However, that also would cause the hibernate interfaces for user space to be enabled, which might confuse user space, because the Xen kernels don't support hibernation. Moreover, it would be wasteful, as it would make the Xen kernels include a substantial amount of code that they would never use. To address this issue introduce new power management Kconfig option CONFIG_HIBERNATE_CALLBACKS, such that it will only select the code that is necessary for the hibernate device callbacks to work and make CONFIG_HIBERNATION select it. Then, Xen save/restore will be able to select CONFIG_HIBERNATE_CALLBACKS without dragging the entire hibernate code along with it. Signed-off-by: Rafael J.

* | | vfs: Re-introduce s_uuid in the superblockLinus Torvalds2011-04-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gaah. When commit be85bccaa5aa reverted the export of file system uuid via /proc/<pid>/mountinfo, it also unintentionally removed the s_uuid field in struct super_block. I didn't mean to do that, since filesystems have been taught to fill it in (and we want to keep it for future re-introduction in the mountinfo file). Stupid of me. This adds it back in.

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 93f1c20bc8cdb757be50566eff88d65c3b26881f. It turns out that libmount misparses it because it adds a '-' character in the uuid string, which libmount then incorrectly confuses with the separator string (" - ") at the end of all the optional arguments. Upstream libmount (in the util-linux tree) has been fixed, but until that fix actually percolates up to users, we'd better not expose this change in the kernel. Let's revisit this later (possibly by exposing the UUID without any '-' characters in it, avoiding the user-space bug).

This became the cause to return "IP_PKTINFO's ->ipi_ifindex == 0". To fix it, this does: 1) Add "int rt_route_iif;" to struct rtable 2) For input routes, always set rt_route_iif to same value as rt_iif 3) For output routes, always set rt_route_iif to zero. Set rt_iif as it is done currently. 4) Change rt_is_{output,input}_route() to test rt_route_iif Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an interrupt occurs, the INT pin is driven low by the MCP251x controller (falling edge) but in some cases the INT pin can be connected to the MPU through a transistor or level translator which inverts this signal.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ipv6 fib lookup can set RT6_LOOKUP_F_IFACE flag to restrict search to an interface, but this flag cannot be set via struct flowi. Also, it cannot be set via ip6_route_output: this function uses the passed sock struct to determine if this flag is required (by testing for nonzero sk_bound_dev_if). Work around this by passing in an artificial struct sk in case 'strict' argument is true. This is required to replace the rt6_lookup call in xt_addrtype.c with nf_afinfo->route().

To some degree that is unavoidable (stacked DM devices force this late checking). But for most DM devices (which aren't stacking on other DM devices) the ideal time to verify all integrity profiles match is during table load. Introduce the notion of an "initialized" integrity profile: a profile that was blk_integrity_register()'d with a non-NULL 'blk_integrity' template. Add blk_integrity_is_initialized() to allow checking if a profile was initialized. Update DM integrity support to: - check all devices with _initialized_ integrity profiles match during table load; uninitialized profiles (e.g. for underlying DM device(s) of a stacked DM device) are ignored. - disallow a table load that would result in an integrity profile that conflicts with a DM device's existing (in-use) integrity profile - avoid clearing an existing integrity profile - validate all integrity profiles match during resume; but if they don't all we can do is report the mismatch (during resume we're past the point of no return) Signed-off-by: Mike Snitzer <snitzer@redhat.com> Cc: Martin K.

| * | usbnet: use eth%d name for known ethernet devicesArnd Bergmann2011-04-021-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The documentation for the USB ethernet devices suggests that only some devices are supposed to use usb0 as the network interface name instead of eth0. The logic used there, and documented in Kconfig for CDC is that eth0 will be used when the mac address is a globally assigned one, but usb0 is used for the locally managed range that is typically used on point-to-point links. Unfortunately, this has caused a lot of pain on the smsc95xx device that is used on the popular pandaboard without an EEPROM to store the MAC address, which causes the driver to call random_ether_address(). Obviously, there should be a proper MAC addressed assigned to the device, and discussions are ongoing about how to solve this, but this patch at least makes sure that the default interface naming gets a little saner and matches what the user can expect based on the documentation, including for new devices. The approach taken here is to flag whether a device might be a point-to-point link with the new FLAG_POINTTOPOINT setting in the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one of the two. The usbnet framework only looks at the MAC address for device naming if both flags are set, otherwise it trusts the flag.
