There are also sparse error spewings on attributes((...)) that are
not in the expected source code location. Three examples:
1. net/sched/cls_api.c, lines 593-611:
return 0;
rtattr_failure: __attribute__ ((unused))
return -1;
}
...
return 0;
rtattr_failure: __attribute__ ((unused))
return -1;
}
These spew:
net/sched/cls_api.c:593:17: error: typename in expression
net/sched/cls_api.c:594:2: error: Expected ; at end of statement
net/sched/cls_api.c:594:2: error: got return
net/sched/cls_api.c:611:17: error: typename in expression
net/sched/cls_api.c:612:2: error: Expected ; at end of statement
net/sched/cls_api.c:612:2: error: got return
net/sched/cls_api.c:593:17: error: undefined identifier '__attribute__'
net/sched/cls_api.c:611:17: error: undefined identifier '__attribute__'
2. in 2.6.21-rc4-mm1 only AFAIK, arch/x86_64/kernel/early-quirks.c, #79:
static struct __initdata chipset early_qrk[] = {
{ PCI_VENDOR_ID_NVIDIA, nvidia_bugs },
{ PCI_VENDOR_ID_VIA, via_bugs },
{ PCI_VENDOR_ID_ATI, ati_bugs },
{}
};
spews:
arch/x86_64/kernel/early-quirks.c:79:15: error: Trying to use reserved word '__attribute__' as identifier
arch/x86_64/kernel/early-quirks.c:79:15: error: Expected ) in function declarator
arch/x86_64/kernel/early-quirks.c:79:15: error: got ".init.data"
3. drivers/kvm/ spews LOTS of mess:
