Revision c812012f9ca7cf89c9e1a1cd512e6c3b5be04b85 authored by Jeff Layton on 25 November 2015, 18:50:11 UTC, committed by Trond Myklebust on 25 November 2015, 20:31:49 UTC
If we pass in an empty nfs_fattr struct to nfs_update_inode, it will (correctly) not update any of the attributes, but it then clears the NFS_INO_INVALID_ATTR flag, which indicates that the attributes are up to date. Don't clear the flag if the fattr struct has no valid attrs to apply.
