svn commit: r264023 - in head/sys: cam/ctl dev/iscsi

[Edward Tomasz Napierala]

Author: trasz
Date: Tue Apr  1 21:47:22 2014
New Revision: 264023
URL: http://svnweb.freebsd.org/changeset/base/264023

Log:
  Instead of "icltx" and "iclrx", use thread names with prefix from upper
  layer, so that one can see which side of the stack the threads are for.
