perf Documentation: Add some more hints to tips.txt

2024-02-02T06:18:18+00:00

Add some (hopefully useful) hints to tips.txt
Also some minor corrections.

Would probably good to make it a reviewer rule that if generally useful
options are added the patch must add an example to tips.txt

scripts/spelling.txt: add "an user" pattern and fix typo instances

2017-02-28T02:43:46+00:00

Fix typos and add the following to the scripts/spelling.txt:

  an user||a user
  an userspace||a userspace

I also added "userspace" to the list since it is a common word in Linux.
I found some instances for "an userfaultfd", but I did not add it to the
list.  I felt it is endless to find words that start with "user" such as
"userland" etc., so must draw a line somewhere.

perf report/top: Add a tip about source line numbers with overhead

2016-10-05T22:47:55+00:00

There is a existing tip as below.

    If you have debuginfo enabled, try: perf report -s sym,srcline

However this tip only describe a condition to use --sort sym,scrline
options.  So there is lack of explanation in the tip. I think that it
would be better to add a tip that exactly explains the feature of --sort
srcline.
