[PATCH v3 0/7] Lazy flush for the auth session

[Pengyu Ma]

Hi Jarkko,

After applied this patchset, the boot time become 8.9 secondes, it's
more reasonable.

But this patchset can't be clean applied to upstream 6.11 kernel.
looks like file tpm2-sessions.c is changed in your code base.

Tested-by: Pengyu Ma <mapengyu at gmail.com>

Thanks,
Pengyu
