[PATCH] profile.c: `schedule' parsing fix
profile=schedule parsing is not quite what it should be. First, str[7] is
'e', not ',', but then even if it did fall through, prof_on =
SCHED_PROFILING would be clobbered inside if (get_option(...)) So a small
amount of rearrangement is done in this patch to correct it.
