mm/khugepaged: remove unneeded shmem_huge_enabled() check
Patch series "A few cleanup patches for khugepaged", v2.
This series contains a few cleaup patches to remove unneeded return value,
use helper macro, fix typos and so on. More details can be found in the
respective changelogs.
This patch (of 7):
If we reach here, khugepaged_scan_mm_slot() has already made sure that
hugepage is enabled for shmem, via its call to hugepage_vma_check().
Remove this duplicated check.
