"Three fixes related to locking:
- fix a SIGKILL issue for RWSEM_GENERIC_SPINLOCK which has been fixed
for the XCHGADD variant already
- plug a potential use after free in the futex code
- prevent leaking a held spinlock in an futex error handling code
path"

README
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.
