From c1d81b1cf937027d23f7e53cdd12328799028c6a Mon Sep 17 00:00:00 2001 From: David Howells Date: Fri, 6 Mar 2015 14:24:37 +0000 Subject: VFS: Fix up some ->d_inode accesses in the chelsio driver Fix up some ->d_inode accesses in the chelsio driver. (1) FILE_DATA() should just be replaced with file_inode(). (2) set_debugfs_file_size() should be removed and debugfs_create_file_size() should be used to create the file.
