[LTP] [PATCH] mkswap01.sh: Add "udevadm trigger" before swap verification

[Yongxin Liu]

Fix: https://github.com/linux-test-project/ltp/issues/458

Sometimes the swap device cannot show up in /dev/disk/by-uuid/
or /dev/disk/by-lable/ due to the issue #458. When this issue
happens, "blkid -c /dev/null" and "ls /dev/disk/by-uuid/" show
different UUID of the device.
