Hi Andrew, Tetsuo has posted patch 1 already [1]. I had some minor concenrs about the changelog but the approach was already OK. Aliaksei came with an alternative patch [2] which also handles double unregistration. I have updated the changelog and moved the syzbot report to the 2nd patch because it is more related to the change there. The patch 1 is prerequisite. Maybe we should just merge those two. I've kept Tetsuo's s-o-b and his original authorship, but let me know if you disagree with the new wording or the additional change, Tetsuo.
The patch 2 is based on Al's suggestion [3] and it fixes sget_userns shrinker registration code. Both of these stalled so can we have them merged finally?
