malloc and free within a single subroutine.
Comments and global explanations on what your code or algorithm does.
When committing a fix for a bug, make the comment of the following form:
```
Reason for bug fix or other message. Fixes bug #1234
```
It is important to write the bug #1234 like that because our program that automatically pulls messages from the git repository to make the ChangeLog looks for that pattern. Obviously the 1234 should be replaced with the number of the bug you actually fixed.

Providing the commit comment line has one of the following keywords (or phrases), it will be ignored:
```
tweak
typo
cleanup
bweb:
regress:
again
.gitignore
fix compilation
technotes
update version
update technotes
update kernstodo
update projects
update releasenotes
update version
update home
update release
update todo
update notes
update changelog
```
Use the following keywords at the beginning of a git commit message
