The patch titled
     hugetlbfs: add NULL check in hugetlb_zero_setup()
has been removed from the -mm tree.  Its filename was
     hugetlbfs-add-null-check-in-hugetlb_zero_setup.patch

This patch was dropped because it was merged into mainline or a subsystem tree

------------------------------------------------------
Subject: hugetlbfs: add NULL check in hugetlb_zero_setup()
From: Akinobu Mita <akinobu.mita@gmail.com>

If hugetlbfs module_init() fails, hugetlbfs_vfsmount is not initialized and
shmget() with SHM_HUGETLB flag will cause NULL pointer dereference.
