Make it __read_mostly while at it. - Link to v2: https://lore.kernel.org/r/[email protected] Changes in v2: - Add a module parameter to enable dma-buf cgroup accounting, disabled by default. - Split system_heap logic in its own commit. - Link to v1: https://lore.kernel.org/lkml/[email protected]/ Signed-off-by: Eric Chanudet <[email protected]> --- Eric Chanudet (2): dma-buf: heaps: add parameter to account allocations using cgroup dma-buf: system_heap: account for system heap allocation in memcg drivers/dma-buf/dma-heap.c | 5 +++++ drivers/dma-buf/heaps/system_heap.c | 7 +++++-- include/linux/dma-heap.h | 2 ++ 3 files changed, 12 insertions(+), 2 deletions(-) --- base-commit: 983d014aafb14ee5e4915465bf8948e8f3a723b5 change-id: 20260102-dmabuf-heap-system-memcg-c86a381d663a Best regards, -- Eric Chanudet <[email protected]>
