Subject: [PATCH 6.1 38/71] selftests/mm: switch to bash from sh

From: Muhammad Usama Anjum <usama.anjum@...labora.com>

[ Upstream commit bc29036e1da1cf66e5f8312649aeec2d51ea3d86 ]

Running charge_reserved_hugetlb.sh generates errors if sh is set to
dash:

/charge_reserved_hugetlb.sh: 9: [[: not found
/charge_reserved_hugetlb.sh: 19: [[: not found
/charge_reserved_hugetlb.sh: 27: [[: not found
/charge_reserved_hugetlb.sh: 37: [[: not found
/charge_reserved_hugetlb.sh: 45: Syntax error: "(" unexpected

Switch to using /bin/bash instead of /bin/sh.  Make the switch for
write_hugetlb_memory.sh as well which is called from
charge_reserved_hugetlb.sh.
