This commit converts extract-stall.sh script's header comment to a
usage() function, and adds an argument check. While in the area, make
this script be executable.
[ paulmck: Strength argument check, remove extraneous comment. ]

This commit adds a script that extracts RCU CPU stall warnings
from console output. The user can optionally specify the number of
lines preceding the stall to output, and also the number of lines of
stall-warning text.

tools/rcu: Add drgn script to dump number of RCU callbacks2021-05-10T22:39:19+00:00Paul E. McKenneypaulmck@kernel.org2021-04-22T18:55:43+00:00urn:sha1:e5bd61e82b7a60c92bc09a618a0d8a612689037b
This commit adds an rcu-cbs.py drgn script that computes the number of
RCU callbacks waiting to be invoked. This information can be helpful
when managing systems that are short of memory and that have software
components that make heavy use of RCU, for example, by opening and
closing files in tight loops. (But please note that there are almost
always better ways to get your job done than by opening and closing
files in tight loops.)
