      [JFFS2] Fix race in post-mount node checking · d96fb997
      David Woodhouse authored
      For a while now, we've postponed CRC-checking of data nodes to be done
      by the GC thread, instead of being done while the user is waiting for
      mount to finish. The GC thread would iterate through all the inodes on
      the system and check each of their data nodes. It would skip over inodes
      which had already been used or were already being read in by
      read_inode(), because their data nodes would have been examined anyway.
      
      However, we could sometimes reach the end of the for-each-inode loop and
      still have some unchecked space left, if an inode we'd skipped was
      _still_ in the process of being read. This fixes that race by actually
      waiting for read_inode() to finish rather than just moving on.
      
      Thanks to Ladislav Michl for coming up with a reproducible test case and
      helping to track it down.
