+Subject: [PATCH] linux-user: Do not define struct sched_attr if libc headers
+ do
+
+glibc 2.41+ has added [1] definitions for sched_setattr and
+sched_getattr functions and struct sched_attr.  Therefore, it needs
+to be checked for here as well before defining sched_attr, to avoid
+a compilation failure.
+
+Define sched_attr conditionally only when SCHED_ATTR_SIZE_VER0 is
+not defined.
