Hello Greg,

Could you please consider backporting to v4.4 the following commit:

commit b5b5b6fe643391209b08528bef410e0cf299b826 Author: Simon Guo wei.guo.simon@gmail.com Date: Fri Oct 7 20:59:40 2016

mm: mlock: avoid increase mm->locked_vm on mlock() when already mlock2(,MLOCK_ONFAULT)

It seems to be a trivial fix for:

Thanks in advance,

Where did you get that git commit id?

It's b155b4fde5bdde9fed439cd1f5ea07173df2ed31 in Linus's tree. Something went really odd on your side here :(
