From: Hugh Dickins Date: Mon, 5 Mar 2007 08:30:28 +0000 (-0800) Subject: [PATCH] shmem and simple const super_operations X-Git-Tag: v2.6.21-rc3~85 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=759b9775c25f5e69aaea8a75c3914019e2dc5539;p=linux-2.6 [PATCH] shmem and simple const super_operations shmem's super_operations were missed from the recent const-ification; and simple_fill_super()'s, which can share with get_sb_pseudo()'s.
