For example, SRCU provides the following: + + srcu-torture: rtc: f8cf46a8 ver: 355 tfle: 0 rta: 356 rtaf: 0 rtf: 346 rtmbe: 0 + srcu-torture: Reader Pipe: 559738 939 0 0 0 0 0 0 0 0 0 + srcu-torture: Reader Batch: 560434 243 0 0 0 0 0 0 0 0 + srcu-torture: Free-Block Circulation: 355 354 353 352 351 350 349 348 347 346 0 + srcu-torture: per-CPU(idx=1): 0(0,1) 1(0,1) 2(0,0) 3(0,1) + +The first four lines are similar to those for RCU. The last line shows +the per-CPU counter state. The numbers in parentheses are the values +of the "old" and "current" counters for the corresponding CPU. The +"idx" value maps the "old" and "current" values to the underlying array, +and is useful for debugging. + USAGE |
