Umh, misunderstanding: I thought you commented on the Irix part. And it's not my patch, it's Jakub Jelineks patch I applied against current 2.5
I don't even see an advantage on having them as filesystem - I just think that the SysV and Posix mqueues should share most of the code. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
