ntb_transport_create_queue() is never called in atomic context. ntb_transport_create_queue() is only called by ntb_netdev_probe(), which is set as ".probe" in struct ntb_transport_client. Despite never getting called from atomic context, ntb_transport_create_queue() calls kzalloc_node() with GFP_ATOMIC, which does not sleep for allocation. GFP_ATOMIC is not necessary and can be replaced with GFP_KERNEL, which can sleep and improve the possibility of sucessful allocation. This is found by a static analysis tool named DCNS written by myself. And I also manually check it Signed-off-by: Jia-Ju Bai <baijiaju1990@gmail.com> Signed-off-by: Jon Mason <jdmason@kudzu.us>
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
