| 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. |
