+From 06d96cee7d9f4d95025ac0988ac3b273ead0061e Mon Sep 17 00:00:00 2001
+From: Jerome Marchand <jmarchan@redhat.com>
+Date: Sun, 18 May 2025 01:12:30 +0200
+Subject: [PATCH] tools/biosnoop: Fix biosnoop pattern option (#5304)
+
+The code to support the block_io tracepoints failed to update some
+code that is used with the -P option. That code changed the second
+argument of __trace_req_completion from 'req' to 'key', but in the
+"#ifdef INCLUDE_PATTERN" block, the use of 'req' remained unchanged.
+Of course, 'key' should be use here too.
+
+Also remove the commented out line of code related to rq_disk.
+
+It fixes the following error:
+$ biosnoop -P
+/virtual/main.c:213:24: error: use of undeclared identifier 'req'
+  213 |         data.pattern = req->__sector == *sector ? SEQUENTIAL : RANDOM;
+      |                        ^
+/virtual/main.c:216:19: error: use of undeclared identifier 'req'
+  216 |     last_sector = req->__sector + data.len / 512;
+      |                   ^
+2 errors generated.
