Behavior that's different from Solaris probably merits investigation, but on its own that's not justification for making a change. It sounds like this isn't a real problem for you, just a result you observed in some tests, so for now I'm not inclined to worry about it very much. If you want to pursue it, you're welcome to make a patch (it's probably just a matter of adjusting those accessmap arrays in fs/nfsd/vfs.c), and you may well be correct to do so, but the patch will need to come with a more persuasive argument. --b. -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
