[PATCH] mm, hugetlb: fix "treat_as_movable" condition in htlb_alloc_mask

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If hugepage_migration_supported() returns true, this renders the
hugepages_treat_as_movable sysctl completely pointless.

Let's keep this behavior optional by switching the if() condition
from || to &&.
