+Subject: [PATCH] locking/rwsem: Add __always_inline annotation to
+ __down_read_common() and inlined callers
+Git-commit: 92cc5d00a431e96e5a49c0b97e5ad4fa7536bd4b
+Patch-mainline: v6.4-rc2
+References: git-fixes
+
+Apparently despite it being marked inline, the compiler
+may not inline __down_read_common() which makes it difficult
+to identify the cause of lock contention, as the blocked
+function in traceevents will always be listed as
+__down_read_common().
+
+So this patch adds __always_inline annotation to the common
+function (as well as the inlined helper callers) to force it to
+be inlined so the blocking function will be listed (via Wchan)
+in traceevents.
+
+Fixes: c995e638ccbb ("locking/rwsem: Fold __down_{read,write}*()")
