[Peter Wemm]

Author: peter

New Revision: 281008
URL: https://svnweb.freebsd.org/changeset/base/281008

Log:
  Remove redundant mtx_lock/unlock in ciss_name_device. This is a guaranteed
  insta-panic on device add/remove.  This is only called from the notify
  thread which already holds the lock while calling this function.
