Please dont use that patch, I will make a new one. Christian - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

I guess this should mostly be a NOP to KVM, right? Yes, currently kvm on x86 has interrupts disabled during vmx and svm. So in_interrupt should be always false on x86. But isn't account_system_time() called via the timer tick interrupt, and never directly from kvm? So in_interrupt() would always be true. The sequence, as I understand it, is: - disable interrupts - set PF_VCPU - switch to guest - exit guest due to timer tick - enable interrupts - dispatch timer tick - account_system_time() With the fine-grained accounting ppc and s390 have, this is different. -- error compiling committee.c: too many arguments to function - This SF.net email is sponsored by: Splunk Inc.
