	Libraries should be listed last on the compiler's command line, so that the linker can look for and find still unresolved symbols. The librt library, required for the shm_* functions, was announced using CFLAGS, which puts the library before the source files, and fails compilation on my system: ====================== gcc -isystem /src/linux-selftests/usr/include -Wall -lrt test_cachestat.c -o /src/linux-selftests/kselftest/cachestat/test_cachestat /usr/bin/ld: /tmp/cceQWO3u.o: in function `test_cachestat_shmem': test_cachestat.c:(.text+0x890): undefined reference to `shm_open' /usr/bin/ld: test_cachestat.c:(.text+0x99c): undefined reference to `shm_unlink' collect2: error: ld returned 1 exit status make[4]: *** [../lib.mk:181: /src/linux-selftests/kselftest/cachestat/test_cachestat] Error 1 ====================== Announce the library using the LDLIBS variable, which ensures the proper ordering on the command line.

2023-06-09	selftests: add selftests for cachestat	Nhat Pham
	Test cachestat on a newly created file, /dev/ files, /proc/ files and a directory. Also test on a shmem file (which can also be tested with huge pages since tmpfs supports huge pages).
