I've started a discussion in Tokio about updating the version of parking_lot (which includes bumping the MSRV to 1.49). tokio-rs/tokio#4456

[clux]

tempted to hold off on this for one version if it's undecided upstream - think we are pretty close to releasing the next version anyway - port forwarding pr in #446 looks ready

[olix0r]

Agreed. Seems fine to pick this up when Tokio releases with the update

[olix0r]

FYI, this will be included in the next Tokio release tokio-rs/tokio#4459

[clux]

well, we have deny failures on parking_lot now anyway in master after #827, kube-client brings in parking_lot 0.12 via tokio 1.17

we can upgrade the kube_runtime pin, but we will still have deny failures the leaf that is pulled in from https://github.com/sfackler/hyper-openssl

    = parking_lot_core v0.8.5
      └── parking_lot v0.11.2
          ├── hyper-openssl v0.9.1
          │   └── kube-client v0.69.0

thinking this is a less detrimental duplicate to have (openssl case only) than the duplicate we currently already have (always, when using kube-runtime) - so we should probably just merge this and put a deny exclude or try to push a bump up to sfackler (the repo hasn't been updated in 14 months though)

[clux]

made a pr upstream to hyper-openssl: sfackler/hyper-openssl#31

[dependabot]

Looks like parking_lot is up-to-date now, so this is no longer needed.
