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

From: Namjae Jeon <namjae.jeon@...sung.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
