svn commit: r267641 - head/sys/cam/ctl

[Alexander Motin]

Author: mav
Date: Thu Jun 19 12:43:41 2014
New Revision: 267641
URL: http://svnweb.freebsd.org/changeset/base/267641

Log:
  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.
  
  MFC after:	2 weeks
