# ipc: remove memcg accounting for sops objects in do_semtimedop() # # Linus proposes to revert an accounting for sops objects in # do_semtimedop() because it's really just a temporary buffer # for a single semtimedop() system call. # # This object can consume up to 2 pages, syscall is sleeping # one, size and duration can be controlled by user, and this # allocation can be repeated by many thread at the same time. # # However Shakeel Butt pointed that there are much more popular # objects with the same life time and similar memory # consumption, the accounting of which was decided to be # rejected for performance reasons. # # Considering at least 2 pages for task_struct and 2 pages for # the kernel stack, a back of the envelope calculation gives a # footprint amplification of <1.5 so this temporal buffer can be # safely ignored. # # The factor would IMO be interesting if it was >> 2 (from the # PoV of excessive (ab)use, fine-grained accounting seems to be # currently unfeasible due to performance impact). # # Link: https://lore.kernel.org/lkml/90e254df-0dfe-f080-011e-b7c53ee7fd20@virtuozzo.com/ #
