The patch titled
shmem and simple const super_operations
has been removed from the -mm tree. Its filename was
shmem-and-simple-const-super_operations.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: shmem and simple const super_operations
From: Hugh Dickins <hugh@xxxxxxxxxxx>
shmem's super_operations were missed from the recent const-ification;
and simple_fill_super()'s, which can share with get_sb_pseudo()'s.
