The variable 'err' is assgigned to an error message if atomic alloc failed, while it has no chance to be printed if is_atomic is true. Here change to print error message too if atomic alloc failed, while avoid to call dump_stack() if that case. Signed-off-by: Baoquan He <bhe@redhat.com> Signed-off-by: Dennis Zhou <dennis@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 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.
