free_anon_vma_name() is missing a check for anonymous shmem VMA which
leads to a memory leak due to refcount not being dropped. Fix this by
calling anon_vma_name_put() unconditionally. It will free vma->anon_name
whenever it's non-NULL.
Fixes: d09e8ca6cb93 ("mm: anonymous shared memory naming")
A cc:stable is appropriate here, yes?
Hmm. The patch we are fixing here was merged in 6.2-rc1. Should I CC
stable to fix the previous -rc branch?
No need for stable if it's not in a release kernel yet.
Commit d09e8ca6cb93 is in 6.1. The fix applies cleanly.
$ git tag --contains d09e8ca6cb93 | grep "^v"
v6.2-rc1
v6.2-rc2
Doesn't look like 6.1 to me.
