When I compiled the tools/testing/selftests/bpf, the following error pops out: uprobe_multi.c: In function ‘trigger_uprobe’: uprobe_multi.c:109:26: error: ‘MADV_PAGEOUT’ undeclared (first use in this function); did you mean ‘MADV_RANDOM’? madvise(addr, page_sz, MADV_PAGEOUT); ^~~~~~~~~~~~ MADV_RANDOM
Including the <linux/linux/mman.h> header file solves this compilation error.
