| 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. |
