[PATCH v4 0/7] f2fs: Add tracepoints support in f2fs filesystem

[PATCH v4 0/7] f2fs: Add tracepoints support in f2fs filesystem

[Namjae Jeon]

From: Namjae Jeon <namjae.jeon@samsung.com>

Add tracepoints in f2fs filesystem for tracing the filesystem
operations for information/debugging purpose if needed. All the
tracepoints are clubbed with respect to functionalities.

Change Log:
v4: Modified the tracepoints as per the review comments of
Jaegeuk Kim. Following tracepoints are added newly:

trace_f2fs_truncate_blocks_enter
trace_f2fs_truncate_blocks_exit
trace_f2fs_truncate_inode_blocks_enter 
trace_f2fs_truncate_inode_blocks_exit
trace_f2fs_truncate_node
trace_f2fs_submit_write_page
trace_f2fs_do_submit_bio
trace_f2fs_write_checkpoint

While some of the tracepoints are modified to add new 
parameters.

v3: Introduced TRACE_EVENT_CONDITION() macro for checking the
condition page->mapping inside the trace point function call as
per Steve's review comment for the patch

v2: Added DECLARE_EVENT_CLASS() macro for combining the similar
type of trace function calls which has same type of arguments.

v1: Introduced the tracepoint functions in f2fs filesystem.

Namjae Jeon (7):
  f2fs: add tracepoints for sync & Inode operations
  f2fs: add tracepoints for truncate operation
  f2fs: add tracepoint for tracing the page i/o operations
  f2fs: add tracepoints for GC threads
  f2fs: add tracepoints to debug the block allocation & fallocate
  f2fs: add tracepoints for write page operations
  f2fs: add tracepoints to debug checkpoint request

Hi, Namjae.

Still I found several inconsistent codes and flaws of information across
the whole patches.
I've finished changing them, so please review the subsequent patches.
Thanks,

Hi Jaegeuk.
First, Thank you for taking the time to fill the gaps :)
I checked all updated patches. Looks good to me ~.
