Well in that case perhaps something else broke. I've seen no such reports of recent regressions in the ramdisk driver.
The two problems of which I am aware are:
a) It loses its brains across umount. Seems that it's very rare that anyone actually cares about this, which is why it has not been fixed in well over a year.
b) It loses data under heavy I/O loads. I _think_ this has been observed only on ppc64 and might be a cache writeback/invalidate thing.
If there are new post-2.6.5 problems then I'm all ears. - 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/
