Hello, This patch series address feedback for a previous patch series sent by me "docs: block: null_blk: enhance document style"[1]. First patch removes a restriction that prevents null_blk to load with (nr_devices == 0). This restriction breaks applications, so it's a bug. I have tested it running the kernel with `null_blk.nr_devices=0`. In the previous series I have changed the type of var nr_devices, but I forgot to change the type at module_param(). The second patch fix that. The third patch uses a cleaver approach to make log messages consistent using pr_fmt and the last one add a note on how to do that at the coding style documentation. Thanks, André Changes since v1: - Add "Fixes" tag at [2/4] - No more headers reordering at [3/4] - Use #undef pr_fmt and KBUILD_MODNAME at [3/4] and [4/4] - Replace "printk.h" for "kernel.h" at [4/4] More details are provided at each patch changelog [1] https://patchwork.kernel.org/project/linux-block/list/?series=172853 André Almeida (4): null_blk: do not fail the module load with zero devices null_blk: match the type of parameter nr_devices null_blk: format pr_* logs with pr_fmt coding-style: add explanation about pr_fmt macro Documentation/process/coding-style.rst | 10 +++++++++- drivers/block/null_blk.h | 4 +++- drivers/block/null_blk_main.c | 24 ++++++++++-------------- drivers/block/null_blk_zoned.c | 6 +++--- 4 files changed, 25 insertions(+), 19 deletions(-) -- 2.23.0
