+Subject: [PATCH] misc/tst-syscall6: fix build with musl and older kenrel
+ headers
+
+The RWF_DSYNC and RWF_HIPRI macros were introduced in kernel version 4.6
+with the preadv2/pwritev2 system calls. musl libc provides its own
+syscall definitions, even when the kernel headers are older. This leads
+to the following build failure:
+
+tst-syscall6.c: In function 'main':
+tst-syscall6.c:32:48: error: 'RWF_DSYNC' undeclared (first use in this function)
+  nio = syscall(SYS_pwritev2, fd, iov, 2, 0, 0, RWF_DSYNC);
+                                                ^~~~~~~~~
+tst-syscall6.c:32:48: note: each undeclared identifier is reported only once for each function it appears in
+tst-syscall6.c:42:58: error: 'RWF_HIPRI' undeclared (first use in this function)
+  nio = syscall(SYS_preadv2, fd, iov, 1, strlen(str0), 0, RWF_HIPRI);
+                                                          ^~~~~~~~~
+
+Make the code depend also on RWF_HIPRI to fix this failure.
