New Revision: 268261
URL: http://svnweb.freebsd.org/changeset/base/268261

Log:
  MFC r267641:
  Add some more CTL_FLAG_ABORT check points.
  
  This should allow to abort commands doing mostly disk I/O, such as VERIFY
  or WRITE SAME.  Before this change CTL_FLAG_ABORT was only checked around
  data moves, which for these commands may not happen for a very long time.
