From 4236a26a6b998c8c4fdc0117b8848a38789c48ae Mon Sep 17 00:00:00 2001 From: wenhuizhang Date: Thu, 13 May 2021 12:55:16 -0400 Subject: cifs: remove deadstore in cifs_close_all_deferred_files() Deadstore detected by Lukas Bulwahn's CodeChecker Tool (ELISA group). line 741 struct cifsInodeInfo *cinode; line 747 cinode = CIFS_I(d_inode(cfile->dentry)); could be deleted. cinode on filesystem should not be deleted when files are closed, they are representations of some data fields on a physical disk, thus no further action is required. The virtual inode on vfs will be handled by vfs automatically, and the denotation is inode, which is different from the cinode.
