Source: linux-2.6
Version: 2.6.32-28
Severity: serious
Hi,
smp_ops was changed in a rather incompatible way in 2.6.32.26, breaking
the kernel ABI:
diff --git a/arch/x86/include/asm/smp.h b/arch/x86/include/asm/smp.h
index 4cfc908..4c2f63c 100644
--- a/arch/x86/include/asm/smp.h
+++ b/arch/x86/include/asm/smp.h
@@ -50,7 +50,7 @@ struct smp_ops {
void (*smp_prepare_cpus)(unsigned max_cpus);
void (*smp_cpus_done)(unsigned max_cpus);
- void (*smp_send_stop)(void);
+ void (*stop_other_cpus)(int wait);
void (*smp_send_reschedule)(int cpu);
int (*cpu_up)(unsigned cpu);
This change was, in turn, willfully ignored (SVN rev 16598) and the kernel
ABI remained at 5.
This breaks external modules like VMware (vmmon) that use the smp_ops
symbol.
Please revert or bump the kernel ABI to 6 to reflect this ABI change.
Thanks,
JB.

With Ian's vote, the outcome is no longer in doubt, and the decision is:
A) The technical committee declines to override the kernel maintenance
team's ABI numbering policy.
