From 9a09c89fdd0e0cebec48d1bb7bc187bf92ae361c Mon Sep 17 00:00:00 2001 From: Baruch Siach Date: Tue, 13 Mar 2018 12:58:59 +0200 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.
