Documentation/trace/events.txt: Remove obsolete sched_signal_send.
'sched_signal_send' doesn't exist in the kernel now. Replace it
with 'signal_generate' so that the example in events.txt can be
executed successfully.
I also change some /debug to /sys/kernel/debug which is debugfs'
default mount directory now(similar to commit 52ad51e).

For example, here's the information displayed for the 'sched_wakeup'
event:

For example:
-# cd /debug/tracing/events/sched/sched_wakeup
+# cd /sys/kernel/debug/tracing/events/sched/sched_wakeup
# echo "common_preempt_count > 4" > filter
A slightly more involved example:
-# cd /debug/tracing/events/sched/sched_signal_send
+# cd /sys/kernel/debug/tracing/events/signal/signal_generate
# echo "((sig >= 10 && sig < 15) || sig == 17) && comm != bash" > filter
If there is an error in the expression, you'll get an 'Invalid
argument' error when setting it, and the erroneous string along with
an error message can be seen by looking at the filter e.g.:
-# cd /debug/tracing/events/sched/sched_signal_send
+# cd /sys/kernel/debug/tracing/events/signal/signal_generate
# echo "((sig >= 10 && sig < 15) || dsig == 17) && comm != bash" > filter
-bash: echo: write error: Invalid argument
# cat filter
