+From: Coly Li <colyli@××××.de>
+Date: Wed, 2 Sep 2020 19:27:08 +0800
+Subject: [PATCH 1/2] bcache-tools: add bcache-status
+
+People request to include bcache-status into bcache-tools package. This
+patch picks bcache-status script from github page of the orginal author
+Darrick J. Wong,
+  https://github.com/djwong/bcache-tools/blob/master/bcache-status
+
+Thanks to Darrick for writing the great bcache-status, and I will keep
+this script being updated from Darrick's repo time to time.
