nedmalloc: work around overzealous GCC 6 warning With GCC 6, the strdup() function is declared with the "nonnull" attribute, stating that it is not allowed to pass a NULL value as parameter. In nedmalloc()'s reimplementation of strdup(), Postel's Law is heeded and NULL parameters are handled gracefully. GCC 6 complains about that now because it thinks that NULL cannot be passed to strdup() anyway. Because the callers in this project of strdup() must be prepared to call any implementation of strdup() supplied by the platform, so it is pointless to pretend that it is OK to call it with NULL. Remove the conditional based on NULL-ness of the input; this squelches the warning. Check the return value of malloc() instead to make sure we actually got the memory to write to. See https://gcc.gnu.org/gcc-6/porting_to.html for details.

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.
Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.
Please read the file INSTALL for installation instructions.
Many Git online resources are accessible from http://git-scm.com/ including full documentation and Git related tools.
See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.
CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).
The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just “subscribe git” in the body to majordomo@vger.kernel.org. The mailing list archives are available at http://news.gmane.org/gmane.comp.version-control.git/, http://marc.info/?l=git and other archival sites.
The maintainer frequently sends the “What's cooking” reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.
The name “git” was given by Linus Torvalds when he wrote the very first version. He described the tool as “the stupid content tracker” and the name as (depending on your mood):
