From 8cbd6f6f7f10c57b27a1388883a6dc5715610600 Mon Sep 17 00:00:00 2001 From: Julius Hemanth Pitti Date: Thu, 19 Mar 2020 17:26:43 -0700 Subject: nfs-utils: Disable statx if using glibc emulation nfs-utils 2.4.1, moves from "stat" to "statx with AT_STATX_DONT_SYNC" in parts of the code. statx is supported in Linux kernel v4.11 and above. For all older kernels glibc emulates statx, and it doesn't support AT_STATX_DONT_SYNC and will return EINVAL. When server uses nfs-utils 2.4.1 on kernel v4.10 and older, mount.nfs4 would fail with error "reason given by server: No such file or directory". Since Linux v4.4 and v4.9 are LTS, its more likely that people would use above combination. This issue has been fixed in nfs-utils 2.4.3 and above. Backporting fix to 2.4.1.
