A new helper function stack_map_calculate_max_depth() that computes the max depth for a stackmap. Changes in v2: - Removed the checking 'map_size % map_elem_size' from stack_map_calculate_max_depth - Changed stack_map_calculate_max_depth params name to be more generic Changes in v3: - Changed map size param to size in max depth helper Changes in v4: - Fixed indentation in max depth helper for args Changes in v5: - Bound back trace_nr to num_elem in __bpf_get_stack - Make a copy of sysctl_perf_event_max_stack in stack_map_calculate_max_depth Changes in v6: - Restrained max_depth computation only when required - Additional cleanup from Song in __bpf_get_stack Link to v5: https://lore.kernel.org/all/[email protected]/ Signed-off-by: Arnaud Lecomte <[email protected]> Acked-by: Yonghong Song <[email protected]> Cc: Song Lui <[email protected]>
