Hi Bruce,
Commit428a23d2bf0ca 'nfsd: skip some unnecessary stats in the v4 case' causes these tests to fail when the filesystem is ext4. It works fine with btrfs and xfs. The reason it fails with EXT4 is because ext4 does not have i_version-supporting. The SB_I_VERSION is not set in the super block so we skip the fh_getattr and just use fh_post_attr which is 0 to fill fh_post_change. I'm not quite sure what's the fix for this. If we skip the fs_getattr
for v4 thenfh_post_attr is 0 which causes the returned change attribute to be 0. -Dai
I've got a fix for this issue scheduled for v5.17, and hopefully
it can be back-ported to stable kernels too.
Thank you Chuck,
