    nfsd: fix failure to set eof in readdir in some situations · 8d7c4203
    J. Bruce Fields authored
    Before 14f7dd63 "[PATCH] Copy XFS
    readdir hack into nfsd code", readdir_cd->err was reset to eof before
    each call to vfs_readdir; afterwards, it is set only once.  Similarly,
    c002a6c7 "[PATCH] Optimise NFS readdir
    hack slightly", can cause us to exit without nfserr_eof set.  Fix this.
    
    This ensures the "eof" bit is set when needed in readdir replies.  (The
    particular case I saw was an nfsv4 readdir of an empty directory, which
    returned with no entries (the protocol requires "." and ".." to be
    filtered out), but with eof unset.)
