The vmalloc test driver(https://lkml.org/lkml/2019/1/2/52) has been added to the linux-next. Therefore i would like to fix some stability issues i identified using it. I explained those issues in detail here: https://lkml.org/lkml/2018/10/19/786 There are two patches, i think they are pretty ready to go with, unless there are any comments from you.
