The group of a network device can be queried or changed from userspace using sysfs. For example, considering sysfs mounted in /sys, one can change the group that interface lo belongs to: echo 1 > /sys/class/net/lo/group Signed-off-by: Vlad Dogaru <ddvlad@rosedu.org> Acked-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S.

Reduce printk() levels to KERN_INFO in netdev_fix_features() as this will be used by ethtool and might spam dmesg unnecessarily. This converts the function to use netdev_info() instead of plain printk(). As a side effect, bonding and bridge devices will now log dropped features on every slave device change.

- Remove CamelCase. - Convert hexadecimals to lower case. - Remove useless comments. Tlan driver contained a name of the function at the end of it in a comment. Remove those comments. - Remove local typedefs. Use real types instead of typedefs in code. - Resolve space issues and reindent. - One warning remain, it's a case where printing a single line involves a number of printk()s.

Allow drivers for multiqueue hardware with flow filter tables to accelerate RFS. The driver must: 1. Set net_device::rx_cpu_rmap to a cpu_rmap of the RX completion IRQs (in queue order). This will provide a mapping from CPUs to the queues for which completions are handled nearest to them. 2. Implement net_device_ops::ndo_rx_flow_steer. This operation adds or replaces a filter steering the given flow to the given RX queue, if possible. 3. Periodically remove filters for which rps_may_expire_flow() returns true.

When initiating I/O on a multiqueue and multi-IRQ device, we may want to select a queue for which the response will be handled on the same or a nearby CPU. This requires a reverse-map of IRQ affinity. Add library functions to support a generic reverse-mapping from CPUs to objects with affinity and the specific case where the objects are IRQs.

Michael Witten and Christian Kujau reported that the autogroup scheduling feature hurts interactivity on their UP systems. It turns out that this is an older bug in the group scheduling code, and the wider appeal provided by the autogroup feature exposed it more prominently. When on UP with FAIR_GROUP_SCHED enabled, tune shares only affect tg->shares, but is not reflected in tg->se->load. The reason is that update_cfs_shares() does nothing on UP. So introduce update_cfs_shares() for UP && FAIR_GROUP_SCHED. This issue was found when enable autogroup scheduling was enabled, but it is an older bug that also exists on cgroup.cpu on UP.

Now BUILD_BUG_ON() can handle optimizable constants, we don't need MAYBE_BUILD_BUG_ON any more. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
-
Rusty Russell authored
BUILD_BUG_ON used to use the optimizer to do code elimination or fail at link time; it was changed to first the size of a negative array (a nicer compile time error), then (in 8c87df45) to a bitfield. This forced us to change some non-constant cases to MAYBE_BUILD_BUG_ON(); as Jan points out in that commit, it didn't work as intended anyway. bitfields: needs a literal constant at parse time, and can't be put under "if (__builtin_constant_p(x))" for example. negative array: can handle anything, but if the compiler can't tell it's a constant, silently has no effect. link time: breaks link if the compiler can't determine the value, but the linker output is not usually as informative as a compiler error. If we use the negative-array-size method *and* the link time trick, we get the ability to use BUILD_BUG_ON() under __builtin_constant_p() branches, and maximal ability for the compiler to detect errors at build time. We also document it thoroughly. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Cc: Jan Beulich <JBeulich@novell.com> Acked-by: Hollis Blanchard <hollisb@us.ibm.com>

Currently only drivers that are built as modules have their versions shown in /sys/module/<module_name>/version, but this information might also be useful for built-in drivers as well. This especially important for drivers that do not define any parameters - such drivers, if built-in, are completely invisible from userspace. This patch changes MODULE_VERSION() macro so that in case when we are compiling built-in module, version information is stored in a separate section. Kernel then uses this data to create 'version' sysfs attribute in the same fashion it creates attributes for module parameters.

commit 3f0d3d01 adds a check for PNP device id to the common tpm_tis_init() function, which in some cases (force=1) will be called without the device being a member of a pnp_dev.

If duration variable value is 0 at this point, it's because chip->vendor.duration wasn't filled by tpm_get_timeouts() yet. This patch sets then the lowest timeout just to give enough time for tpm_get_timeouts() to further succeed.
