New Revision: 314469
URL: https://svnweb.freebsd.org/changeset/base/314469

Log:
  Update tw_cl_share.h to allow 255 LUNs
  
  TW_CL_MAX_NUM_LUNS should not be 16 but I presume 255. I have a 3ware
  controller with more than 16 volumes (LUN's) and otherwise all LUN's
  above the 16'th are not working.
