f2fs: add f2fs_io_tracer support This patch adds: o initial trace.c and trace.h with skeleton functions o Kconfig and Makefile to activate this feature Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

f2fs: add key functions for f2fs_io_tracer This patch adds two key functions to trace process ids and IOs. The basic idea is to 1. remain process ids, pids, in page->private. 2. show pids in IO traces. So, later we can retrieve process information according to IO traces.

f2fs: add sbi and page pointer in f2fs_io_info This patch adds f2fs_sb_info and page pointers in f2fs_io_info structure. With this change, we can reduce a lot of parameters for IO functions. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

f2fs: add spin_lock to cover radix operations in IO tracer This patch adds spin_lock to cover radix tree operations in IO tracer. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>

f2fs: add f2fs_destroy_trace_ios to free radix tree This patch removes radix tree after finishing tracing IOs. Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
