> struct sl_inode_path_map
>
>Prepare for the "path" being a fake path and not the real server-side
>path where we won't be able to vfs_stat_fsp() this fake path. Luckily we already
>got stat info for the object in mds_add_result() so we can just pass stat info
>from there.

>The client learns about the share root path prefix â real server-side of fake in
>the future â in an initial handshake in the "share_path" out argument of the
>mdssvc_open() RPC call, so the client can use this path to convert the absolute

>There is however an additional twist: the macOS Spotlight server prefixes this

>
>  /System/Volumes/Data/foo/bar/dir/file
>
>So macOS does return the full server-side path too, just prefixed with an
>additional path. This path prefixed can be queried by the client in the
>mdssvc_cmd() RPC call with an Spotlight command of "fetchPropertiesForContext:"
>and the path is returned in a dictionary with key "kMDSStorePathScopes". Samba
>just returns "/" for this.
>
>Currently the mdscli library doesn't issue this Spotlight RPC
>request (fetchPropertiesForContext), so this is added in this commit. In the
>end, all search result paths are stripped of the combined prefix
>
>  kMDSStorePathScopes + share_path (from mdssvc_open).
>
>eg
>
>  kMDSStorePathScopes = /System/Volumes/Data
>  share_path = /foo/bar
>  search result = /System/Volumes/Data/foo/bar/dir/file
>  relative path returned by mdscli = dir/file
>
>Makes sense? :)
