Cgroup HugeTLB in kernel 5.16

[sunu]

Is there any reason you disabled cgroup hugetlb support in 5.16 kernels?
# CONFIG_CGROUP_HUGETLB is not set
You had it enabled in previous kernels.

Also can you enable tpm support?

Thanks

1st, tpm support is enabled as module, proof it yourself with grep -i tpm /boot/config-$(uname -r)
2nd, with the next kernel CONFIG_CGROUP_HUGETLB is enabled again.

1st, tpm support is enabled as module, proof it yourself with grep -i tpm /boot/config-$(uname -r)

Doesn´t seem to be enough:
systemd[1]: dev-tpm0.device: Job dev-tpm0.device/start timed out.
systemd[1]: Timed out waiting for device /dev/tpm0.

slh´s aptosid kernel picks it up:
systemd[1]: Found device /dev/tpm0.
systemd[1]: Starting TPM2 Access Broker and Resource Management Daemon...

lsmod | grep tpm shows nothing
Digging deeper it seems that it uses tpm_crb driver

I could enable it, but why to hell you want the evil TPM?

Nothing of immediate use, personally. But I see it can be used in encryption if anyone is inclined to, for example https://wiki.archlinux.org/title/Trusted_Platform_Module
