[PATCH 3/3] f2fs: enhance scalability of trace macro
From: Chao Yu
Date: Wed May 03 2017 - 12:01:53 EST
From: Chao Yu <yuchao0@xxxxxxxxxx>
Use __print_flags in show_bio_op_flags and show_cpreason instead of
__print_symbolic, it enables tracer function traverses and shows all
bits in the flag.
Additionally, add missing REQ_FUA into F2FS_OP_FLAGS.
