commit09b204eb9dupstream. The three bugs are here: __func__, s3a_buf->s3a_data->exp_id); __func__, md_buf->metadata->exp_id); __func__, dis_buf->dis_data->exp_id); The list iterator 's3a_buf/md_buf/dis_buf' will point to a bogus position containing HEAD if the list is empty or no element is found. This case must be checked before any use of the iterator, otherwise it will lead to a invalid memory access. To fix this bug, add an check. Use a new variable '*_iter' as the list iterator, while use the old variable '*_buf' as a dedicated pointer to point to the found element.

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.
