+Subject: [PATCH v3] add renameat2 linux syscall wrapper
+To: musl@lists.openwall.com
+Cc: Rich Felker <dalias@libc.org>
+
+This syscall is available since Linux 3.15 and also implemented in glibc
+from version 2.28. It is commonly used in filesystem or security contexts.
+
+Constants RENAME_NOREPLACE, RENAME_EXCHANGE, RENAME_WHITEOUT are guarded by
+_GNU_SOURCE as with glibc.
+
+Signed-off-by: Tony Ambardar <Tony.Ambardar@gmail.com>
+---
+v2 -> v3:
+ * call SYS_renameat first if applicable
+ * drop unneeded error code handling
+
+v1 -> v2:
+ * align related constants
+ * drop 'int' from 'unsigned int'
+ * add fallback to SYS_renameat where applicable
