+Subject: [PATCH] libsanitizer: Fix build with glibc 2.42
+
+The termio structure will be removed from glibc 2.42.  It has
+been deprecated since the late 80s/early 90s.
+
+Cherry-picked from LLVM commit 59978b21ad9c65276ee8e14f26759691b8a65763
+("[sanitizer_common] Remove interceptors for deprecated struct termio
+(#137403)").
