+Subject: [PATCH] fix: net: skb: introduce kfree_skb_reason() (v5.15.58..v5.16)
+
+See upstream commit :
+
+ commit c504e5c2f9648a1e5c2be01e8c3f59d394192bd3
+ Author: Menglong Dong <imagedong@tencent.com>
+ Date: Sun Jan 9 14:36:26 2022 +0800
+
+ net: skb: introduce kfree_skb_reason()
+
+ Introduce the interface kfree_skb_reason(), which is able to pass
+ the reason why the skb is dropped to 'kfree_skb' tracepoint.
+
+ Add the 'reason' field to 'trace_kfree_skb', therefor user can get
+ more detail information about abnormal skb with 'drop_monitor' or
+ eBPF.
+
+ All drop reasons are defined in the enum 'skb_drop_reason', and
+ they will be print as string in 'kfree_skb' tracepoint in format
+ of 'reason: XXX'.
+
+ ( Maybe the reasons should be defined in a uapi header file, so that
+ user space can use them? )
