Nam Cao <namcao@linutronix.de> says: In /proc/PID/stat, there is the kstkesp field which is the stack pointer of a thread. While the thread is active, this field reads zero. But during a coredump, it should have a valid value. However, at the moment, kstkesp is zero even during coredump. The first commit fixes this problem, and the second commit adds a selftest to detect if this problem appears again in the future. * patches from https://lore.kernel.org/r/cover.1735805772.git.namcao@linutronix.de: selftests: coredump: Add stackdump test fs/proc: do_task_stat: Fix ESP not readable during coredump Link: https://lore.kernel.org/r/cover.1735805772.git.namcao@linutronix.de Signed-off-by: Christian Brauner <brauner@kernel.org>
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.
