Building with link time optimizations produces a false-positive section mismatch warning: WARNING: vmlinux.o(.data+0xf8c8): Section mismatch in reference from the variable driver_template.lto_priv.6915 to the function .init.text:sym53c416_detect() The variable driver_template.lto_priv.6915 references the function __init sym53c416_detect() If the reference is valid then annotate the variable with __init* or __refdata (see linux/init.h) or name the variable: *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console The ->detect callback is always entered from the init_this_scsi_driver() init function, but apparently LTO turns the optimized direct function call into an indirect call through a non-__initdata pointer. All drivers using init_this_scsi_driver() are for ancient hardware, and most don't mark the detect() callback as __init(), so I'm just removing the annotation here to kill off the warning instead of doing a larger rework.

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.
