drivers/gpu/drm/drm_syncobj.c:202:4-14: ERROR: function drm_syncobj_find_signal_pt_for_point called on line 390 inside lock on line 389 but uses GFP_KERNEL Find functions that refer to GFP_KERNEL but are called with locks held. Generated by: scripts/coccinelle/locks/call_kern.cocci v2: syncobj->timeline still needs protect. v3: use a global signaled fence instead of re-allocation. v4: Don't need moving lock. Don't expose func. v5: rename func and directly return. Tested by: syncobj_wait and ./deqp-vk -n dEQP-VK.*semaphore* with lock debug kernel options enabled.

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.
