the patches still refer to the new attribute as FATTR4_WORD2_UMASK which is
confusing.  Can we please call it FATTR4_WORD2_MODE_UMASK as in the patches in
this series to better match what the attribute is called in
draft-ietf-nfsv4-umask-02.

Other than refreshing the patches and renaming FATTR4_WORD2_UMASK to
FATTR4_WORD2_MODE_UMASK and NFS_CAP_UMASK to NFS_CAP_MODE_UMASK, the patches
here are the same.

Thanks,
Andreas
