By replacing, we would reduce the use of 'global' current on code, relying more in the contents of kvm struct. On code, I found that in kvm_create_vm() there is: kvm->mm = current->mm; And that on every kvm_*_ioctl we have tests like that: if (kvm->mm != current->mm) return -EIO; So this change would be safe. I split the changes in 3 patches, so it would be easier to read and reject separated parts. If decided that squashing is better, I see no problem doing that.
