+Subject: [PATCH] sched_attr: Do not define for glibc >= 2.41
+
+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
+
+Define sched_attr conditionally on SCHED_ATTR_SIZE_VER0
+
+Fixes builds with glibc/trunk
+
