Unfortunately, due to an dev_pm_opp locking interaction with mm->mmap_sem, we need to do pm get before aquiring obj locks, otherwise we can have anger lockdep with the chain: opp_table_lock --> &mm->mmap_sem --> reservation_ww_class_mutex For an explicit fencing userspace, the impact should be minimal as we do all the fence waits before this point. It could result in some needless resumes in error cases, etc. Signed-off-by: Rob Clark <robdclark@chromium.org> Reviewed-by: Kristian H.

README
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.
