      fs: fix superblock iteration race · 57439f87
      npiggin@suse.de authored
      list_for_each_entry_safe is not suitable to protect against concurrent
      modification of the list. 6754af64 introduced a race in sb walking.
      
      list_for_each_entry can use the trick of pinning the current entry in
      the list before we drop and retake the lock because it subsequently
      follows cur->next. However list_for_each_entry_safe saves n=cur->next
      for following before entering the loop body, so when the lock is
      dropped, n may be deleted.
