Once locks are added, binder_ref's will only be accessed safely with the proc lock held. Refactor the inc/dec paths to make them atomic with the binder_get_ref* paths and node inc/dec. For example, instead of: ref = binder_get_ref(proc, handle, strong); ... binder_dec_ref(ref, strong); we now have: ret = binder_dec_ref_for_handle(proc, handle, strong, &rdata); Since the actual ref is no longer exposed to callers, a new struct binder_ref_data is introduced which can be used to return a copy of ref state.

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.
