[PATCH 0/2] Move erasing to the GC thread.

Current JFFS2 erases blocks from write_super() which is
problematic as a reboot while erasing will make the
umount hang until all blocks has been erased.

These patches address this problem by moving the erasing
to the GC task instead, leaving write_super() to only
handle dirty data.

Joakim Tjernlund (2):
  jffs2: Move erasing from write_super to GC.
  jffs2: Make jffs2_erase_pending_trigger() initiate GC.
