selftests: rcutorture: Use "grep -E" instead of "egrep"
The latest version of grep is deprecating the egrep command, so that
its output contains warnings as follows:
egrep: warning: egrep is obsolescent; using grep -E
Fix this using "grep -E" instead.
sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/testing/selftests/rcutorture`
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
