swapinfo print major/minor number when device name too long
Hi, I enabled swap encryption by adding the "crypt" option to "/etc/fstab", therefore the auto configured swap device has a rather long name ("swap-<serno>.<slice><part>"), which seems, I think, cause problem for the "swapinfo"/"pstat" tool. For example:
dfly# ls -l /dev/mapper/swap-WD-WCAS25235448.s1b
crw-r----- 1 root operator 65, 0x1e11000f Oct 21 08:26 /dev/mapper/swap-WD-WCAS25235448.s1b
Device 1K-blocks Used Avail Capacity Type
/dev/#C65:0x1e11000f 16777216 1141708 15635508 7% Interleaved
By default, "swapinfo" should print the device "name" instead of such major/minor numbers.

Hi, I just did several more tests to confirm this issue. When the swap device name gets longer, the printed name by "swapinfo" will first be truncated, then the major/minor numbers is printed instead.
Please see the attached screenshot for my tests.
