+Subject: [PATCH] docs: Don't define duplicate label in
+ qemu-block-drivers.rst.inc
+
+Sphinx requires that labels within documents are unique across the
+whole manual.  This is because the "create a hyperlink" directive
+specifies only the name of the label, not a filename+label.  Some
+Sphinx versions will warn about duplicate labels, but even if there
+is no warning there is still an ambiguity and no guarantee that the
+hyperlink will be created to the right target.
+
+For QEMU this is awkward, because we have various .rst.inc fragments
+which we include into multiple .rst files.  If you define a label in
+the .rst.inc file then it will be a duplicate label.  We have mostly
+worked around this by not putting labels into those .rst.inc files,
+or by adding "insert a label" functionality into the hxtool extension
+(see commit 1eeb432a953b0 "doc/sphinx/hxtool.py: add optional label
+argument to SRST directive").
+
+Unfortunately in commit 7f6314427e78 ("docs/devel: add a codebase
+section") we accidentally added a duplicate label, because not all
+Sphinx versions warn about the mistake.
+
+In this case the link was only from the developer docs codebase
+summary, so as the simplest fix for the stable branch, we drop
+the link entirely.
