+Subject: [PATCH] libstdc++: Mark non-exported function always_inline
+ [PR105671]
+
+This new function was added for gcc 11.1 but is not exported from the
+shared library. Depending on inlining decisions, its callers might get
+inlined but an external definition be needed for this function. That
+then fails to link.
+
+Since we can't add the export to the gcc-11 release branch now, mark it
+always_inline. We can consider exporting it for gcc-13 if/when we bump
+the shared library version (and maybe also for gcc-12 which is currently
+at the same version as trunk). For now, the attribute will solve the
+problem on all affected branches. The function is small enough that
+force-inlining it shouldn't cause problems.
+
+libstdc++-v3/ChangeLog:
+
+	PR libstdc++/105671
+	* include/std/sstream (basic_stringbuf::_M_high_mark): Add
+	always_inline attribute.
+
+(cherry picked from commit de57440858591a88e8fd7ba2505ca54546c86021)
