Subject: [PATCH 07/14] drm/i915: use pagefault_disabled() to check for
|
|
disabled pagefaults
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.0/patches-4.0.8-rt6.tar.xz
|
|
|
|
Now that the pagefault disabled counter is in place, we can replace
|
|
the in_atomic() check by a pagefault_disabled() checks.
