From 0f2a84f41aff6cefd1bc768738159d0cacea2f2d Mon Sep 17 00:00:00 2001 From: Himangi Saraogi Date: Mon, 13 Oct 2014 15:53:18 -0700 Subject: fs/befs/btree.c: remove typedef befs_btree_node The Linux kernel coding style guidelines suggest not using typedefs for structure types. This patch gets rid of the typedef for befs_btree_node. The following Coccinelle semantic patch detects the case. @tn1@ type td; @@ typedef struct { ... } td; @script:python tf@ td << tn1.td; tdres; @@ coccinelle.tdres = td; @@ type tn1.td; identifier tf.tdres;
