Round #2. O_EXCL patches will be postponed to 6.19 as they need some restructuring. E.g., there's in-between series regression breaking the user space as lack of O_EXCL flag handling causes obviously unconditional O_EXCL. As per Chris' feedback, commands fail because it is based on Google's a non-standard proprietary TPM alike implementation. And the issue is not PC Client Profile specific. "typical profiles" are fine when they become "typical profiles". The null key can be verified with vendor certificate tied keys, and there's challenge-response process using them for certifying any other key by a remote party. Performance hit on generation aside, if really starting to cut hairs null keys are the most secure option, and it's a non-debatable fact: they have shortest expiration times as seed changes per power cycle. Based on this TCG_TPM2_HMAC is disabled from defconfig exactly for the sake of the performance issues.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
