The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:
egrep: warning: egrep is obsolescent; using grep -E
fix this up by moving the related file to use "grep -E" instead.
sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/memory-model`
Here are the steps to install the latest grep:
wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz
tar xf grep-3.8.tar.gz
cd grep-3.8 && ./configure && make
sudo make install
export PATH=/usr/local/bin:$PATH

Looks good to me.

Paul, JFYI, this patch doesn't apply cleanly on -rcu dev due to
a couple of changes in the lkmm-dev.2022.10.18c branch.
Thanks, Akira
Hi Akira,
Thanks for your review, sorry for that, let me rebase on
linux-rcu.git dev and send v2 later.
Thanks,
Tiezhu
