Subject: mm/shmem: fix input and output inconsistencies
Date: Fri, 28 Jun 2024 11:23:27 +0800

Commit 19eaf44954df ("mm: thp: support allocation of anonymous multi-size
THP") added mTHP support for anonymous shmem.  We can configure different
policies through the multi-size THP sysfs interface for anonymous shmem.

But when we configure the "advise" policy of
/sys/kernel/mm/transparent_hugepage/hugepages-xxxkB/shmem_enabled, we
cannot write the "advise", but write the "madvise", which is unreasonable.
We should keep the output and input values consistent, which is more
convenient for users.
