+Subject: [PATCH] udev: correctly handle partition #16 and later
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+If a zvol has more than 15 partitions, the minor device number exhausts
+the slot count reserved for partitions next to the zvol itself. As a
+result, the minor number cannot be used to determine the partition
+number for the higher partition, and doing so results in wrong named
+symlinks being generated by udev.
+
+Since the partition number is encoded in the block device name anyway,
+let's just extract it from there instead.
+
+Fixes: #15904
