Alexander Aring says: ==================== sched: act: ife: UAPI checks and performance tweaks this patch series contains at first a patch which adds a check for IFE_ENCODE and IFE_DECODE when a ife act gets created or updated and adding handling of these cases only inside the act callback only. The second patch use per-cpu counters and move the spinlock around so that the spinlock is less being held in act callback. The last patch use rcu for update parameters and also move the spinlock for the same purpose as in patch 2. Notes: - There is still a spinlock around for protecting the metalist and a rw-lock for another list. Should be migrated to a rcu list, ife possible. - I use still dereference in dump callback, so I think what I didn't got was what happened when rcu_assign_pointer will do when rcu read lock is held. I suppose the pointer will be updated, then we don't have any issue here. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
