From 1fe0c0230a7c2d5f4061e681a3f3be9512446d23 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Wed, 19 Sep 2012 15:49:51 +0100 Subject: [PATCH] vfs: delete surplus inode NULL check Each iteration of d_delete we reload inode from dentry->d_inode and then call S_ISDIR(inode-i_mode), so inode cannot possibly be NULL shortly afterwards unless something went horribly wrong.
