Eric Sandeen a8f48a9561 [PATCH] ext3/4: don't do orphan processing on readonly devices 
If you do something like:

  # touch foo
  # tail -f foo &
  # rm foo
  # <take snapshot>
  # <mount snapshot>

you'll panic, because ext3/4 tries to do orphan list processing on the
readonly snapshot device, and:

  kernel: journal commit I/O error
  kernel: Assertion failure in journal_flush_Rsmp_e2f189ce() at journal.c:1356: "!journal->j_checkpoint_transactions"
  kernel: Kernel panic: Fatal exception

for a truly readonly underlying device, it's reasonable and necessary
to just skip orphan list processing.
