[PATCH 00/17] fs/squashfs: fix memory leaks and introduce exists() function

[Richard Genoud]

This patch series fix several memory leaks, some use of dangling
pointers (leading to cpu freeze) and finally introduce the exists()
function for squashfs.
This function enable testing the existance of a file, which is mandatory
for using the distro_bootcmd
Those fixes have been cut into several patches to be easier to review
