Subject: selftests/mm: restore hidden hugetlb reservation scenarios
Date: Tue, 14 Jul 2026 10:16:30 +0800

A stray 'continue' in the main loop of charge_reserved_hugetlb.sh made the
"more than reservation", "more than cgroup limit", and "multiple cgroups"
scenarios unreachable, so they never ran.

Remove it so the first two run again.  The third,
run_multiple_cgroup_test(), is separately broken -- a backslash
line-continuation breaks its local declarations and its hugetlb
reservation accounting does not charge as expected -- and has never run in
CI; skip it explicitly with a comment until fixed.  Also correct two `[[
"$method" == 2"" ]]` typos (harmless empty-string concatenation) to plain
`2`.
