Subject: torture: Fix kvm.sh --datestamp regex check
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=114e4a4b4884c14ebd35874cbe3e1ca0d38efa5d;p=linux.git

torture: Fix kvm.sh --datestamp regex check

Some versions of grep are happy to interpret a nonsensically placed "-"
within a "[]" pattern as a dash, while others give an error message.
This commit therefore places the "-" at the end of the expression where
it was supposed to be in the first place.
