The freeze_all_ptr check in filesystems_freeze_callback() introduced by commita3f8f86627("power: always freeze efivarfs") is reverse which quite confusingly causes all file systems to be frozen when filesystem_freeze_enabled is false. On my systems it causes the WARN_ON_ONCE() in __set_task_frozen() to trigger, most likely due to an attempt to freeze a file system that is not ready for that. Add a logical negation to the check in question to reverse it as appropriate. Fixes:a3f8f86627("power: always freeze efivarfs") Cc: 6.18+ <stable@vger.kernel.org> # 6.18+ Signed-off-by: Rafael J.

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.
