[PATCH] samples/bpf: use %lu format specifier for unsigned long values
Posted by Colin Ian King 1 year, 12 months ago
Currently %ld format specifiers are being used for unsigned long
values. Fix this by using %lu instead. Cleans up cppcheck warnings:

warning: %ld in format string (no. 1) requires 'long' but the argument
type is 'unsigned long'. [invalidPrintfArgType_sint]
