xfrm_init_tempstate is always called from within rcu read side section. We can thus use a simpler function that doesn't call rcu_read_lock again. While at it, also make xfrm_init_tempstate return value void, the return value was never tested. A followup patch will replace remaining callers of xfrm_state_get_afinfo with xfrm_state_afinfo_get_rcu variant and then remove the 'old' get_afinfo interface.

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.
