That reminds me of something else I had in mind to debug that the writer counts are okay: we should probably add a check in permission that we have an elevated writercount on the vfsmount/sb. Of course we'll need some way to overrid it for access(), which means passing down a flag to it or something. - To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
