In the following patches queue and stack maps (FIFO and LIFO datastructures) will be implemented. In order to avoid confusion and a possible name clash rename stack_map_ops to stack_trace_map_ops Signed-off-by: Mauricio Vasquez B <redacted> --- include/linux/bpf_types.h | 2 +- kernel/bpf/stackmap.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-)
