    Subject[PATCH 3/5] tmpfs: handle MPOL_LOCAL mount option properly
    Date
    commit 71fe804b6d5 (mempolicy: use struct mempolicy pointer in
    shmem_sb_info) added mpol=local mount option. but its feature is
    broken since it was born. because such code always return 1 (i.e.
    mount failure).

    This patch fixes it.
