Compatibility with newer linux kernels

[MarDiehl]

according to the release notes, the issues with TCmalloc is resolved for Linux kernels 7.0.14 and later.

I have kernel 7.1.5 (on Arch Linux if that matters), but the docker container does not work:

podman run --rm -v nomad_oasis_mongo:/data/db docker.io/mongo:8.0.28 mongod
{"t":{"$date":"2026-08-05T04:59:17.653Z"},"s":"F",  "c":"CONTROL",  "id":12257600,"ctx":"main","msg":"MongoDB cannot start: Linux kernel versions 6.19 and newer has a known incompatibility with this version of MongoDB. See https://jira.mongodb.org/browse/SERVER-121912 for more information."}

would it be possible to fix the check and only refuse to start on affected kernel versions?

Note: originally discussed on FAIRmat-NFDI/nomad-distro-template#245

Seems like this version guard might be too broad in 8.0.28:

• https://github.com/mongodb/mongo/blob/dc5344b376fdfab0fe5b2982f125c056ab0abcd8/src/mongo/db/startup_check_rseq.cpp#L65

    return major < 6 || (major == 6 && minor < 19);

And seemingly partly fixed in:

• mongodb/mongo@19a7dfe
• https://jira.mongodb.org/browse/SERVER-125742

Not sure if it would be fixed in the upcoming 8.0.29?

Is this a duplicate of #762?

(either way, it's not something we'll fix in the image -- it's something that'll need to be fixed in MongoDB itself)
