[PATCH rcu 02/13] torture: Permit multiple space characters in kvm.sh --kconfig argument
Posted by neeraj.upadhyay@kernel.org 3 months ago
From: "Paul E. McKenney" <paulmck@kernel.org>

The straightforward way of doing bash substitution for optional strings
leaves a pair of space characters, which the kvm.sh --kconfig option
rejects as ill-formed.  This commit therefore changes the corresponding
regular expression to accommodate more than one space character between
successive Kconfig options.
