This series aimes to handle a bug in the Barebox jffs2 driver where the
system crashes once a second unmounting is performed when more than one
jffs2 file system were mounted at the same time at one point.

- The first patch "introduce reference counting at probe" solves the
  initial issue.

- The second patch "remove unnecessary slab cache structure" performs a
  cleanup on the respective code with the opportunity for simplification
  being taken.
