Subject: [PATCH] sleepgraph.py: parse unfished cpu exec line
exist the below case in ftrace file:
sleepgraph-6508 [003] .... 18197.824037: tracing_mark_write: ps - xxx..., lock_torture_wr-94 169,lock_torture_wr-95 143,lock_tort
sleepgraph-6508 [003] .... 18197.824043: tracing_mark_write: ure_wr-96 189,lock_torture_wr-97 174,lock_torture_wr-98 160,lock_torture_st-99 1
lock_torture_wr-96 was split to different line due to limited buffer
size(1k) set in kernel, check this case and re-parse the unfinished
line.
