From: Darrick J. Wong <djwong@kernel.org>

Find all the places where we call umount(1) directly and convert all of
those to _umount calls as well.

sed \
 -e 's/\([[:space:]]\)umount\([[:space:]]*"\$\)/\1_umount\2/g' \
 -e 's/\([[:space:]]\)umount\([[:space:]]*\$\)/\1_umount\2/g' \
 -e 's/^umount\([[:space:]]*"\$\)/_umount\1/g' \
 -e 's/^umount\([[:space:]]*\$\)/_umount\1/g' \
 -i $(git ls-files tests common check)
