This reverts commit e5671dfa. After a follow up discussion with Michal, it was agreed it would be better to leave the kmem controller with just the tcp files, deferring the behavior of the other general memory.kmem.* files for a later time, when more caches are controlled. This is because generic kmem files are not used by tcp accounting and it is not clear how other slab caches would fit into the scheme. We are reverting the original commit so we can track the reference. Part of the patch is kept, because it was used by the later tcp code. Conflicts are shown in the bottom. init/Kconfig is removed from the revert entirely. Signed-off-by: NGlauber Costa <glommer@parallels.com> Acked-by: NMichal Hocko <mhocko@suse.cz> CC: Kirill A.

A known Out Of Order (OOO) problem hurts SFQ when timer changes perturbation value, since all new packets delivered to SFQ enqueue might end on different slots than previous in-flight packets. With round robin delivery, we can thus deliver packets in a different order. Since SFQ is limited to small amount of in-flight packets, we can rehash packets so that this OOO problem is fixed. This rehashing is performed only if internal flow classifier is in use. We now store in skb->cb[] the "struct flow_keys" so that we dont call skb_flow_dissect() again while rehashing.

module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option.

This patch adds the ethtool callbacks necessary to change the rss indirection table from userspace. Should the number of interrupts change (e.g. across a close / open call, or through a reset) and any one of the indirection table values fall out-of-range, the driver will reset the indirection table to a default layout.
