[Bug 300717] [NEW] kerneltop reports wrong map line on 2.6.27-7 ubuntu kernel

[PetiePooo]

Public bug reported:

Binary package hint: kerneltop

Some lines in Ubuntu's 2.6.27-7 kernel (8.10) exceed the 128 character
limit hardcoded in kerneltop.c, giving the "wrong map line" error
message on the next line number as seen below.  Increasing S_LEN to 144
seems to fix it.

pn at lh:~/Desktop$ sudo kerneltop
