From a02cd8e4e091201cb395a805a9f3e2a9981cae37 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Wed, 7 Aug 2019 17:01:13 +0000 Subject: 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.
