The recent fix to ensure atomicity of lookup and allocation inadvertently broke the pool refill mechanism, so that debugobject OOMs now in certain situations. The reason is that the functions which got updated no longer invoke debug_objecs_init(), which is now the only place to care about refilling the tracking object pool. Restore the original behaviour by adding explicit refill opportunities to those places. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmRWoFATHHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYocNID/9e1fU2Nf32woHokzBGgARKb69Kl/hb 6yVdMpOnZtxmluheJLnqCWI4WbAB6NjulEMFv+KkwRZ+QndBKVEo8NMZ9RjbXDBb HEehI6DvsqRDjaytOLEZj+/8afcZ7bUBKk7JuUK+y5B1gZViazfp1eF3hpiKsIV9 aowpH6c9lL/9sPgFe2qpp21MUmNTUQbHpz0vbYC0QjqSEU2zTlu8p//P6VLA3xpl qoh8Gu5qo/L8lPspN2v8TRVXdiqH67J+KpbGO9IuUQWYPQqFdc6WchhHwomAk8nr Nyn9Q1Lred96pTdW3B0Cumnxuf0VPt4X/uQxPSP0kCo/h0Q0Mh6fq59Z66H/Mhjk TAvM52w3VzfTmQB6WgaCD1HyRRqIK5Nd+XqXnenCkHN4kjmGXNLg9MUGxua5CVgF iQTSRYtN18rF9OevDOFGzsEig2RN1JFi9MnJg9Q/L8SoDUn5ZUfhPaSA/HcOBnSe m+9aeRxlb0hAP7+upFKsJkDYzJTtbP6LSx6qqZMyQWqYdsUVHpdiPtJpXb7mLIqQ wo83i/Ohq8+dF6ykd89ZcKJ8vLBrnE1rPFKKmvS5ov1eRt/hZbtR3tmMviCNna0M 2nrJE2fKClbs8Dmc6NNboJdz51ASgZEi32XmdFkATiuZqiD1id7ne0f85ju7DHD9 sOjfo4ZtIKD/Fw== =/0Kc -----END PGP SIGNATURE----- Merge tag 'core-debugobjects-2023-05-06' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull debugobjects fix from Thomas Gleixner: "A single fix for debugobjects: The recent fix to ensure atomicity of lookup and allocation inadvertently broke the pool refill mechanism, so that debugobject OOMs now in certain situations.

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.
