![]() Change the prototype of qed_hw_err_notify() with the following: * constify "fmt" argument according to printk() declarations; * anontate it with __cold attribute to move the function out of the line; * annotate it with __printf() attribute; This eliminates W=1+ warning: drivers/net/ethernet/qlogic/qed/qed_hw.c: In function ‘qed_hw_err_notify’: drivers/net/ethernet/qlogic/qed/qed_hw.c:851:3: warning: function ‘qed_hw_err_notify’ might be a candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format] len = vsnprintf(buf, QED_HW_ERR_MAX_STR_SIZE, fmt, vl); ^~~ as well as saves some code size: add/remove: 0/0 grow/shrink: 2/4 up/down: 40/-125 (-85) Function old new delta qed_dmae_execute_command 1680 1711 +31 qed_spq_post 1104 1113 +9 qed_int_sp_dpc 3554 3545 -9 qed_mcp_cmd_and_union 1896 1876 -20 qed_hw_err_notify 395 352 -43 qed_mcp_handle_events 2630 2577 -53 Total: Before=368645, After=368560, chg -0.02% __printf() will also be helpful with catching bad format strings and arguments.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
