From 077bf22b5cf233863826afbfa4af9b18650a832d Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Wed, 11 Sep 2013 14:20:19 -0700 Subject: mm: do_mmap_pgoff: cleanup the usage of file_inode() Simple cleanup. Move "struct inode *inode" variable into "if (file)" block to simplify the code and avoid the unnecessary check.
