  Do not translate the IN_ACCESS inode flag into the IN_MODIFIED while filesystem
  is suspending/suspended. Doing so may result in deadlock. Instead, set the
  (new) IN_LAZYACCESS flag, that becomes IN_MODIFIED when suspend is lifted.
  
  Change the locking protocol in order to set the IN_ACCESS and timestamps
  without upgrading shared vnode lock to exclusive (see comments in the
  inode.h). Before that, inode was modified while holding only shared
  lock.
