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.

This directory contains for the "file system" library. All supported file systems live under this tree.
Currently the supported file systems in this library are:
-
IMFS or In Memory File System
This is the only root file system on RTEMS at the moment. It supports files, directories, device nodes and mount points. It can also be configured to be the miniIMFS.
-
TFTP and FTP filesystem require networking support.
-
DEVFS or Device File system
-
DOSFS, a FAT 12/16/32 MSDOS compatible file system.
-
NFS Client, can mount NFS exported file systems.
-
PIPE, a pipe file system.
-
RFS, The RTEMS File System.
