jbd2: Use tracepoints for history file The /proc/fs/jbd2/<dev>/history was maintained manually; by using tracepoints, we can get all of the existing functionality of the /proc file plus extra capabilities thanks to the ftrace infrastructure. We save memory as a bonus. Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
