Re: [Crash-utility] [patch 1/1] fix incomplete FILENAME in "swap"command

From: Lin Feng Shen <shenlinf(a)cn.ibm.com&gt; dump_swap_info() invokes get_pathname() to get the file name of swap device. If swap_vfsmnt isn't defined but old_block_size is defined in kernel struct swap_info_struct(e.g. 2.6 kernel), 0 is passed as vfsmnt to get_pathname(). In this case, get_pathname() won't go up to the parent vfsmnt, so the file name of swap space is shown incompletely.
