The original import version of the JFFS2 sources was Linux v3.11
(September 2013). Update the JFFS2 sources to Linux v4.17.
The Git command to generate the patches is:
{{{
git format-patch v3.11..v4.17 -- 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/compr_rubin.c
fs/jffs2/compr_zlib.c fs/jffs2/debug.c fs/jffs2/debug.h fs/jffs2/erase.c
fs/jffs2/gc.c fs/jffs2/jffs2_fs_i.h fs/jffs2/jffs2_fs_sb.h
fs/jffs2/nodelist.c fs/jffs2/nodelist.h fs/jffs2/nodemgmt.c
fs/jffs2/read.c fs/jffs2/readinode.c fs/jffs2/scan.c fs/jffs2/summary.h
fs/jffs2/write.c fs/jffs2/xattr.h
}}}
We need a source file transformation in the patches:
{{{
sed -i 's%/fs/jffs2%/cpukit/libfs/src/jffs2/src%g' 00*
}}}
To support the first commit:

Subject: [PATCH 01/24] fs/jffs2: use rbtree postorder iteration helper
instead
of opencoding
Use rbtree_postorder_for_each_entry_safe() to destroy the rbtree instead
of opencoding an alternate postorder iteration that modifies the tree

we have to a postorder iterator to the red-black tree support code.
The remaining 23 patches are easy to apply.
