This patch deprecates f2fs_trace_io, since f2fs uses page->private more broadly,
resulting in more buggy cases.

f2fs: Use the correct style for SPDX License Identifier2020-05-08T13:55:55+00:00Nishad Kamdarnishadkamdar@gmail.com2020-04-25T13:19:08+00:00urn:sha1:d29fbcdb051fbe8e6aee87dd5a7df723f299494d
This patch corrects the SPDX License Identifier style in
header files related to F2FS File System support.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used).

Remove the verbose license text from f2fs files and replace them with
SPDX tags. This does not change the license of any of the code.

f2fs: add sbi and page pointer in f2fs_io_info2015-05-28T22:41:32+00:00Jaegeuk Kimjaegeuk@kernel.org2015-04-23T21:38:15+00:00urn:sha1:05ca3632e5a73b493b27ec3e2a337885563abff0
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.

f2fs: add key functions for f2fs_io_tracer2015-01-10T01:02:24+00:00Jaegeuk Kimjaegeuk@kernel.org2014-12-18T03:51:57+00:00urn:sha1:0e689d036952a6018ed5f5c1aee7697f5c57cea1
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.
