Applied to the bpf tree. Thanks.
From: Hou Tao <houtao1@huawei.com> Hi, The patchset fixes two reported warning in cpu-map when running xdp_redirect_cpu and some RT threads concurrently. Patch #1 fixes the warning in __cpu_map_ring_cleanup() when kthread is stopped prematurely. Patch #2 fixes the warning in __xdp_return() when there are pending skbs in ptr_ring. Please see individual patches for more details. And comments are always welcome. Regards, Tao Hou Tao (2): bpf, cpumap: Make sure kthread is running before map update returns bpf, cpumap: Handle skb as well when clean up ptr_ring kernel/bpf/cpumap.c | 35 +++++++++++++++++++++-------------- 1 file changed, 21 insertions(+), 14 deletions(-)
