ltp: Add "udevadm trigger" before swap verification in mkswap01.sh
Swap verification sometimes fails due to race condition with udev. This is a known issue: https://github.com/linux-test-project/ltp/issues/458. "udevadm trigger" forces udev to sync up device events with kernel. Signed-off-by: Yongxin Liu <yongxin.liu@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

+Subject: [PATCH] mkswap01.sh: Add "udevadm trigger" before swap verification
+
+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.
+
+Upstream-Status: Submitted [https://patchwork.ozlabs.org/patch/1193414]
