+Subject: [PATCH] Fix: ext4_discard_preallocations changed in linux 6.8.0-rc3
+
+See upstream commit:
+
+    commit f0e54b6087de9571ec61c189d6c378b81edbe3b2
+    Author: Kemeng Shi <shikemeng@huaweicloud.com>
+    Date:   Fri Jan 5 17:21:02 2024 +0800
+
+        ext4: remove 'needed' in trace_ext4_discard_preallocations
+
+        As 'needed' to trace_ext4_discard_preallocations is always 0 which
+        is meaningless. Just remove it.
