Pull request overview
Updates OpenVMM’s pinned OpenHCL Linux kernel release to 6.18.0.5, aligning both the Nix kernel fetch and Flowey pipeline version constants. This is intended to pick up an upstream fix for the VTL2 try_grab_folio warning / associated Hyper-V GuestBVT failure.
Changes:
- Bump OpenHCL kernel version from
6.18.0.4→6.18.0.5in the Nix kernel package definition. - Update all corresponding per-branch/arch kernel tarball SHA256 hashes for the new release.
- Update Flowey’s
OPENHCL_KERNEL_{DEV,STABLE}_VERSIONconstants to6.18.0.5.

This passes both openvmm, hvlite pipelines. |

Are you sure the storvsp flakiness is related to a kernel update and not preexisting flakiness? |
Yes, there was a corner case caught by that test, and I could see the function i am modifying in the new change. It’s actually a race condition so it is not reproduced every time. |
