Pull percpu fix from Tejun Heo: "Douglas found and fixed a ref leak bug in percpu_ref_tryget[_live](). The bug is caused by storing the return value of atomic_long_inc_not_zero() into an int temp variable before returning it as a bool. The interim cast to int loses the upper bits and can lead to false negatives. As percpu_ref uses a high bit to mark a draining counter, this can happen relatively easily. Fixed by using bool for the temp variable" * 'for-4.10-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu: percpu-refcount: fix reference leak during percpu-atomic transition
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
