Analysis of an rcutorture callback-based forward-progress test failure was hampered by the lack of ->cblist segment lengths. This commit therefore adds this information, so that what would have been ".W85620.N." (there are some callbacks waiting for grace period sequence number 85620 and some number more that have not yet been assigned to a grace period) now prints as ".W2(85620).N6." (there are 2 callbacks waiting for grace period 85620 and 6 not yet assigned to a grace period). Note that "D" (done), "N" (next and not yet assigned to a grace period, and "B" (bypass, also not yet assigned to a grace period) have just the number of callbacks without the parenthesized grace-period sequence number. In contrast, "W" (waiting for the current grace period) and "R" (ready to wait for the next grace period to start) both have parenthesized grace-period sequence numbers. Signed-off-by: Paul E.
