In situations where the GPU is mostly idle, all or nearly all buffer objects will be in the inactive list. But if the system is under memory pressure (from something other than GPU), we could still get a lot of shrinker calls. Which results in traversing a list of thousands of objs and in the end finding nothing to shrink. Which isn't so efficient. Instead split the inactive_list into two lists, one inactive objs which are shrinkable, and a second one for those that are not. This way we can avoid traversing objs which we know are not shrinker candidates. v2: Fix inverted logic think-o Signed-off-by: Rob Clark <robdclark@chromium.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.
