+Subject: [PATCH] copy: do not refuse to copy a swap file
+
+* src/copy.c (sparse_copy): Fallback to read() if copy_file_range()
+fails with ETXTBSY.  Otherwise it would be impossible to copy files
+that are being used as swap.  This used to work before introducing
+the support for copy_file_range() in coreutils.  (Bug#48036)
