Using a dedicated Kconfig option for enabling debugging means the user may be forced to recompile their kernel in order to gather debugging information, which is inconvenient. Replace custom debugging infrastructure with standard logging functions, taking advantage of dynamic debug. Replace a pr_info() call inside an ACPI callback with an acpi_handle_info() call. The following mapping was used: - FUJLAPTOP_DBG_ERROR -> acpi_handle_err() - FUJLAPTOP_DBG_WARN -> acpi_handle_info() / dev_info() - FUJLAPTOP_DBG_INFO -> acpi_handle_debug() - FUJLAPTOP_DBG_TRACE -> acpi_handle_debug() / dev_dbg() This means that some events which used to only be logged when the user explicitly requested it will now be logged by default: - ACPI method evaluation errors, - unknown ACPI notification codes, - unknown hotkey scancodes. The first type of events should happen rarely, if ever at all. The rest is interesting from driver development perspective as their presence in the logs will mean the driver is unaware of certain events, handling of which should be implemented.

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.
