      [JFFS2] Fix potential memory leak of dead xattrs on unmount. · 2ad8ee71
      David Woodhouse authored 
      An xattr_datum which ends up orphaned should be freed by the GC 
thread. But if we umount before the GC thread is finished, or if we 
mount read-only and the GC thread never runs, they might never be 
freed. Clean them up during unmount, if there are any left.

      [JFFS2] Fix BUG() caused by failing to discard xattrs on deleted files. · 8ae5d312
      David Woodhouse authored 
      When we cannot mark nodes as obsolete, such as on NAND flash, we end up 
having to delete inodes with !nlink in jffs2_build_remove_unlinked_inode().
However, jffs2_build_xattr_subsystem() runs later than this, and will
attach an xref to the dead inode. Then later when the last nodes of that
dead inode are erased we hit a BUG() in jffs2_del_ino_cache() 
because we're not supposed to get there with an xattr still attached to 
the inode which is being killed.

The simple fix is to refrain from attaching xattrs to inodes with zero 
nlink, in jffs2_build_xattr_subsystem(). It's it's OK to trust nlink 
here because the file system isn't actually mounted yet, so there's no 
chance that a zero-nlink file could actually be alive still because 
it's open.

      [JFFS2] Remove broken insert_point optimisation in jffs2_add_tn_to_tree() · 96dd8d25
      David Woodhouse authored 
      The original code would remember, during the first pass over the tree,
a suitable place to start the insertion from when we eventually come
to add a new node.

The optimisation was broken, and we sometimes ended up inserting a new
node in the wrong place because we started the insertion from the wrong
point.

Just ditch the optimisation and start the insertion from the root of the
tree, for now. I'll try it again when I'm feeling cleverer.
