The deadlock detection code drops into an infinite scheduling loop while still holding rt_mutex::wait_lock, which rightfully triggers a 'scheduling in atomic' warning. Unlock it before that. -----BEGIN PGP SIGNATURE----- iQJHBAABCgAxFiEEQp8+kY+LLUocC4bMphj1TA10mKEFAmbLKh0THHRnbHhAbGlu dXRyb25peC5kZQAKCRCmGPVMDXSYoSh0D/sHm7YsexyVAXRxtm1vCJ1rE+ditn/K X60QuH8EyLa2abUY9xKKKaM3YuE+4juN1dyej6uBcET8n9olqGQn0pyxukTDy3Hq Khy7OIAzYfGd7J0kJXA6DHMWAi16e4GduMcDYCw0BwYCQG4D1Ybe/lfsm0mgdcd/ aLFSD8/+oAK7bIWy9VE4wXUPT51v7iFnwajvcKsOL1c3u2StF6A0zCLbjkU5Di20 6Ko4f+B8dh3Bh9yIP/uiwHQHdVUjXp5Y9pVuFLemC8BqGVrwMi71jEEFYQva+evU UTQ8VCbhxIAcz6pqWYA3P5WeqFIQLAXq5UNJLK+63qm/Wf4eoaXNhK+Nr2fCigYu R6T+H5nx2WATATXfPORgfHYgHWwyWaj6nUPK0kaJYUTHFK5Nlg/ir5siqE/Gz9qq ldajnvKpheeuu6rsrdHdJrdI84XVOmjeAJ+5A8i7VMv2jEE50txlxXKt5jeVt2yE xm2+NABT4Dlycf/56e6OYZUEADQfX1YlvFGBQe1UYpcmOC1nTKaWWeQ1xlA3ZR92 plUgXLtRSKaZ3vEFQ3L+/1w0Af3P3/mapb+IgTxW/FEt8WAw6UuwBS9gMZDOhTI+ GZF0EFj8tUmTNDcWkNAu3m3y5Qmp3iVFYBbYXmyJdKVRJbaMu/uq51JnOOIxmaLf L6KovDUg8eF3bQ== =B3iX -----END PGP SIGNATURE----- Merge tag 'locking-urgent-2024-08-25' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull locking fix from Thomas Gleixner: "A single fix for rt_mutex.

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.
