Pull workqueue fix from Tejun Heo: "This is a fix for an old bug in workqueue. Workqueue used a mutex to arbitrate who gets to be the manager of a pool. When the manager role gets released, the mutex gets unlocked while holding the pool's irqsafe spinlock. This can lead to deadlocks as mutex's internal spinlock isn't irqsafe. This got discovered by recent fixes to mutex lockdep annotations. The fix is a bit invasive for rc6 but if anything were wrong with the fix it would likely have already blown up in -next, and we want the fix in -stable anyway" * 'for-4.14-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: replace pool->manager_arb mutex with a flag
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.
