+This tests several things related to the patching of modules:

+- 'kpatch_string' tests the referencing of a symbol which is outside the

+
+- alternatives patching (.altinstructions)
+
+- paravirt patching (.parainstructions)
+
+- jump labels (5.8+ kernels only) -- including dynamic printk

+From: Julien Thierry <jthierry@redhat.com>
+Date: Wed, 6 May 2020 14:30:57 +0100
+Subject: [PATCH] Symbol version change
+
+This change causes:
+1) Some exported symbols in drivers/base/core.c to see their CRCs
+   change.
+2) Changes usb_get_dev() referencing a get_device() whose CRC has
+   changed, causing the symbol and the new CRC to be included in the
+   __version section of the final module.
+
+This makes the final module unloadable for the target kernel.
+
+See "Exported symbol versioning" of the patch author guide for more
+detail.
