Add SYNC_FILE_RANGE_WRITE_AND_WAIT from Linux 5.2 to bits/fcntl-linux.h.
This patch adds the SYNC_FILE_RANGE_WRITE_AND_WAIT constant from Linux
5.2 (a new name for a combination of existing bits, not actually a new
kernel interface) to bits/fcntl-linux.h.
Tested for x86_64.
* sysdeps/unix/sysv/linux/bits/fcntl-linux.h [__USE_GNU]
(SYNC_FILE_RANGE_WRITE_AND_WAIT): New macro.
