The panic function disables the local interrupts, preemption, and all other processors. When the invoked mtdoops needs to erase a used page, calling schedule_work() to do it will not work. Instead, just call mtdoops_erase function immediately. Tested: ~# echo c > /proc/sysrq-trigger [ 171.654759] sysrq: Trigger a crash [ 171.658325] Kernel panic - not syncing: sysrq triggered crash ......

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.
