This commit fixes a lockdep false positive in synchronize_rcu() that can otherwise occur during early boot. Theis fix simply avoids invoking lockdep if the scheduler has not yet been initialized, that is, during that portion of boot when interrupts are disabled. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEbK7UrM+RBIrCoViJnr8S83LZ+4wFAmOeXj8THHBhdWxtY2tA a2VybmVsLm9yZwAKCRCevxLzctn7jPmZEACaI5JqO6Dr2U4HojJJBYEfLVaSYxDp JrUi5D5WzzZidyjM2fyyZZkdRVQ24i1aV2H/fbLoIIH/smYjE/KLEFHQmclpphw5 BSOyapotjdt5YhIavvAeOjdUd7jPyMqhbDVnwzjnblhUD1ObLVlhIs8Pjn7/03sF gzlIhYgp3EL7GenT9j9kud2FwWP+wrVQ7SdJ+Ni/WAHYO8860xQAmFXH/07bYzx7 fbp5iPkCOSSUoRMw/qQ8s7CE3XhBNKufv1BtcvV/uxEtutfV1qvEQBv/l2RBd0Vg wOVBZnWXze+7IUx13M90R/d04Nn7RaGwon6xBMlvIwL3qzEj8x/r1FYz7zZhQPkv wwChAxFHQACnLCZSu48WBtVrawNdZHM57KHUK4rloAbrK92FpVznhQU+5pBDy4c6 rfY2my+SNO4kWvePEg/2fd8aQycrZr99fK/ojCIerEn8MNboxuVOYTjzy0qtUcVT yJ/80O8ADI3QL/NRhjMFWgEnBDbHN1PcGhiRoutApdLQkg/UPTJjCRZ7ibmIFYY2 ViW3cSndr/f0I7sOex2EILHwiZ2bUKiwyeTW6vWuFl/7MEWsvpJaWoUxXgQj99Bt ncAOaxtmmuhbwrOCt2kab90A0c/thNx9kNYYIkG3vUNcSRzyHQtg3ydEljBpaTFR OzhrqdUA7W9Sfg== =UKUo -----END PGP SIGNATURE----- Merge tag 'rcu-urgent.2022.12.17a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu Pull RCU fix from Paul McKenney: "This fixes a lockdep false positive in synchronize_rcu() that can otherwise occur during early boot.

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 Restructured Text 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.
