linux-toradex.git/fs/f2fs/trace.c, branch v4.5 Linux kernel for Apalis and Colibri modules f2fs: add sbi and page pointer in f2fs_io_info 2015-05-28T22:41:32+00:00 Jaegeuk Kim jaegeuk@kernel.org 2015-04-23T21:38:15+00:00 05ca3632e5a73b493b27ec3e2a337885563abff0 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 key functions for f2fs_io_tracer 2015-01-10T01:02:24+00:00 Jaegeuk Kim jaegeuk@kernel.org 2014-12-18T03:51:57+00:00 0e689d036952a6018ed5f5c1aee7697f5c57cea1 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.
