Thank you, Jan. Do you mean this: ERROR: Macros with multiple statements should be enclosed in a do - while loop #208: FILE: testcases/kernel/syscalls/sched_setaffinity/sched_setaffinity.h:37: +#define CPU_ALLOC(ncpus) malloc(sizeof(cpu_set_t)); \ +if (ncpus > CPU_SETSIZE) { \ + tst_brkm(TCONF, cleanup, \ + "Your libc does not support masks with %ld cpus", ncpus); \ +} ? If so, I think I can't do it, because I need to assign CPU_ALLOC() to a variable....
