  • 156f5a780   debugfs: Fix terminology inconsistency of dir name to mount debugfs filesystem. ... Browse Code »

    Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/"
    directory name to mount debugfs filesystem for ftrace according to
    ./Documentation/tracers/ftrace.txt file.

    And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is
    existed in kernel source like ftrace, DRM, Wireless, Documentation,
    Network[sky2]files to mount debugfs filesystem.

    debugfs means debug filesystem for debugging easy to use by greg kroah
    hartman. "/sys/kernel/debug/" name is suitable as directory name
    of debugfs filesystem.
    - debugfs related reference: http://lwn.net/Articles/334546/

    Fix inconsistency of directory name to mount debugfs filesystem.

    * From Steven Rostedt
    - find_debugfs() and tracing_files() in this patch.

  • f4a2a0d9a   ftrace: add a script to produce a hierarchical view of a function trace ... Browse Code »

    This script parses a function trace and then produces a hierarchical
    view of the function call stack after processing it into a tree.

    Changes on V2 thanks to the trace sent by Steven:

    - Support both the files "trace" and "trace_pipe" (comments and space
    differences)

    - Correct the mini HOW-TO at the beginning.
