erp_memwait only occurs in seldom memory pressure situations. The typical case never uses the associated timer and thus also does not need to initialize the timer. Also, we don't want to re-initialize the timer each time we re-use an erp_action in zfcp_erp_setup_act() [see also v4.14-rc7 commitab31fd0ce6("scsi: zfcp: fix erp_action use-before-initialize in REC action trace") for erp_action life cycle]. Hence, retain the lazy inintialization of zfcp_erp_action.timer in zfcp_erp_strategy_memwait(). Add an empty line after declarations in zfcp_erp_timeout_handler() and zfcp_fsf_request_timeout_handler() even though it was also missing before the timer conversion.

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.
