+
+    btrfs: trace: Remove unnecessary fs_info parameter for btrfs__reserve_extent event class
+
+    fs_info can be extracted from btrfs_block_group_cache, and all
+    btrfs_block_group_cache is created by btrfs_create_block_group_cache()
+    with fs_info initialized, no need to worry about NULL pointer
+    dereference.

+ (4.19)
+
+See upstream commit:
+
+  commit d6f19938eb031ee2158272757db33258153ae59c

+
+    net: expose sk wmem in sock_exceed_buf_limit tracepoint
+
+    Currently trace_sock_exceed_buf_limit() only show rmem info,
+    but wmem limit may also be hit.
+    So expose wmem info in this tracepoint as well.
+
+    Regarding memcg, I think it is better to introduce a new tracepoint(if
+    that is needed), i.e. trace_memcg_limit_hit other than show memcg info in
+    trace_sock_exceed_buf_limit.
