November 2019 01:19:30 Betreff: [PATCH] Revert "jffs2: Fix possible null-pointer dereferences in jffs2_add_frag_to_fragtree()"
This reverts commit f2538f999345405f7d2e1194c0c8efa4e11f7b3a. The patch stopped JFFS2 from being able to mount an existing filesystem with the following errors:
jffs2: error: (77) jffs2_build_inode_fragtree: Add node to tree failed -22 jffs2: error: (77) jffs2_do_read_inode_internal: Failed to build final fragtree for inode #5377: error -22

5.4 cannot mount (some?) jffs2 filesystems without this fix. Hou pointed this out[1] a while back but the fix didn't make it in. It's still broken in -next.
queued into -next.
Thanks, //richard
