Use "error" will cause a bug for the following code of error out. I will update it in the new version. thanks, Kinglong Mee -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Did you ever send the update for this? I don't seem to have it in my inbox.

Set rlimit for NFS's files is useless right now. For local process's rlimit, it should be checked by nfs client. The same, CIFS also call inode_change_ok checking rlimit at its client in cifs_setattr_nounix() and cifs_setattr_unix(). v2, same as v1.
