f2fs: cleanup trace event of f2fs_submit_page_{m,}bio with DECLARE_EVENT_CLASS
This patch adds missing parameter _type_ for trace_f2fs_submit_page_bio, then use DECLARE_EVENT_CLASS/DEFINE_EVENT_CONDITION pair to cleanup some trace event code related to f2fs_submit_page_{m,}bio. Additionally, after we remove redundant code, size of code can be reduced: text data bss dec hex filename 176787 8712 56 185555 2d4d3 f2fs.ko.org 174408 8648 56 183112 2cb48 f2fs.ko Signed-off-by: Chao Yu <chao2.yu@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
