[openib-general] [PATCH 1/7] libibverbs: Implement new method for finding and loading device-specific drivers

(gdb) n
295                     if (dent->d_type != DT_REG)
(gdb) p *dent
$10 = {d_ino = 446638, d_off = 1541991424, d_reclen = 32, d_type = 0 '\0',
  d_name = "mthca.driver\000\b\uffff\006\000\000\000\000\000\001\uffff\uffff[\000\000\000\000 \000\000cxgb3.driver", '\0' <repeats 211 times>}
