( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1255473?usp=email ) Change subject: FSAL: mounted_on_fileid as an attribute, and from VFS for mount points ...................................................................... FSAL: mounted_on_fileid as an attribute, and from VFS for mount points The mounted_on_fileid of a file system root must be the inode number of the directory it is mounted on (RFC 8881 5.8.2.23). Ganesha returned the root's own fileid. Every ZFS dataset root is fileid 34, so Linux clients saw nested file systems as directory cycles, and find and du skipped them. Add the optional FSAL attribute ATTR4_MOUNTED_ON_FILEID. Ganesha asks for it only from FSALs that provide it, or MDCACHE would never find it cached. VFS and XFS take it from readdir() for mount points. GETATTR doesn't read the parent, so when Ganesha reads the mount table it records the mount point inode of each nested file system, read once through "..". knfsd returns the same values.
