When running on 5.3 or 5.4 kernels and mounting a Netapp filer via NFSv3 and accessing the .snapshot directory, "fileid changed" errors appear in dmesg. Reverting these 2 patches solves the issue: eb3d8f42231aec: NFS: Fix inode fileid checks in attribute revalidation code 7e10cc25bfa0dd: NFS: Don't refresh attributes with mounted-on-file information Various condition checks changed around printing that error in these commits, but I'm unclear whether the errors are spurious or something I should actually be concerned about. Thoughts? Phil
