For kmem_cache with SLAB_TYPESAFE_BY_RCU, the freeing trace stack at calling kmem_cache_free() is more useful. While the following stack is meaningless and provides no help: freed by task 46 on cpu 0 at 656.840729s: rcu_do_batch+0x1ab/0x540 nocb_cb_wait+0x8f/0x260 rcu_nocb_cb_kthread+0x25/0x80 kthread+0xd2/0x100 ret_from_fork+0x34/0x50 ret_from_fork_asm+0x1a/0x30 Link: https://lkml.kernel.org/r/20240812095517.2357-1-dtcccc@linux.alibaba.com Signed-off-by: Tianchen Ding <dtcccc@linux.alibaba.com> Reviewed-by: Marco Elver <elver@google.com> Cc: Alexander Potapenko <glider@google.com> Cc: Dmitry Vyukov <dvyukov@google.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.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.
