Subject: [PATCH 0/3] Replace current->mm by kvm->mm on powerpc/kvm
Date: Mon, 23 Sep 2019 21:24:06 +0000 [thread overview]
Message-ID: <20190923212409.7153-1-leonardo@linux.ibm.com> (raw)
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.
Best regards,
