[PATCH 3/4] fs: Give dentry to inode_change_ok() instead of inode
Tim Gardner

Wed Mar 17 17:16:26 UTC 2021
From: Jan Kara <jack at suse.cz>
CVE-2015-1350
inode_change_ok() will be resposible for clearing capabilities and IMA
extended attributes and as such will need dentry. Give it as an argument
to inode_change_ok() instead of an inode. Also rename inode_change_ok()
to setattr_prepare() to better relect that it does also some
modifications in addition to checks.
