Subject: nfs-utils: v3 mounts broken due to statx() returning EINVAL

we have some user reporting that NFS v3 mounts are broken
when using glibc-2.29 and linux-4.9.x (4.9.128) because
statx() with mask=STATX_BASIC_STATS returns EINVAL. 

Looks like this isn't happening with <nfs-utils-2.4.1 or
newer kernels.

The following workaround was confirmed to be working:

--- a/support/misc/xstat.c	2019-06-24 21:31:55.260371592 +0200
+++ b/support/misc/xstat.c	2019-06-24 21:32:29.098777436 +0200
@@ -47,6 +47,8 @@
 			statx_copy(statbuf, &stxbuf);
 			return 0;
+		if (errno == EINVAL)
+			errno = ENOSYS;
 		if (errno == ENOSYS)
 			statx_supported = 0;
 	} else


At the moment I have no clue whether this is kernel/glibc or
nfs-utils related; if the patch is safe to apply...

Any help is appreciated. Thanks!
