This directory contains a port of the JFFS2 file system from Linux v5.9.

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 -- \
    include/uapi/linux/jffs2.h \
    fs/jffs2/LICENCE \
    fs/jffs2/acl.h \
    fs/jffs2/build.c \
    fs/jffs2/compr.c \
    fs/jffs2/compr.h \
    fs/jffs2/compr_rtime.c \

    fs/jffs2/jffs2_fs_sb.h \

    fs/jffs2/summary.h \
    fs/jffs2/wbuf.c \
    fs/jffs2/write.c \
    fs/jffs2/xattr.h

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

  sed -i 's%/include/uapi%/cpukit/libfs/src/jffs2/include%g' 00*
  sed -i 's%/fs/jffs2%/cpukit/libfs/src/jffs2/src%g' 00*
