JFFS2 uses the high values of the unsigned flash offset in a raw node reference as special identifiers and specifies them using negative integer literals. This disables those errors for non-RTEMS source and constrains such comparisons in RTEMS code to avoid larger reworks of the JFFS2 upstream source.
Updating
This directory contains a port of the JFFS2 file system from Linux.
To update to a newer Linux version use this command in a Git clone of Linux to generate the relevant patches:
git format-patch v6.1..v9.99 -- \

fs/jffs2/acl.h \

The patches need a transformation of file paths from Linux to RTEMS:
