It may be optimized by the compiler, or have a microscopic performance improvement. In some cases, also changed allocation size to be sizeof some struct or type instead of a pointer - easier to read. In some cases, removed redundant strlen() calls by saving the result into a variable. 1. Only done for the straightforward cases. There's room for improvement. 2. Please review carefully, especially for string allocation, with the terminating NULL string. Only compile-tested! updates: bz#1193929 Original-Author: Yaniv Kaul <ykaul@redhat.com> Signed-off-by: Yaniv Kaul <ykaul@redhat.com> Signed-off-by: Amar Tumballi <amarts@redhat.com> Change-Id: I16274dca4078a1d06ae09a0daf027d734b631ac2
