As definitions of O_* macros provided by various libc implementations are usually less reliable than those provided by kernel headers, switch to use kernel's fcntl.h header. * open.c: Include <asm/fcntl.h> instead of <fcntl.h>. Remove O_LARGEFILE fallback definitions assuming that the kernel headers provide them. * xlat/open_mode_flags.in: Add __O_SYNC after O_SYNC. Add O_TMPFILE and __O_TMPFILE before O_DIRECTORY. Remove "O_TMPFILE & ~O_DIRECTORY". * tests/open.c: Include <asm/fcntl.h> instead of <fcntl.h>. Remove workarounds for libc O_TMPFILE implementations. * tests/openat.c: Include <asm/fcntl.h> instead of <fcntl.h>. (test_mode_flag): New function. (main): Use it to check decoding of all access modes and file flags. * tests/gen_tests.in (openat): Add -a option. Co-Authored-by: Eugene Syromyatnikov <evgsyr@gmail.com>
