If anyone has any objections, please let us know. Turns out this patch introduces a worse regression than it fixes. The bug that the patches fixes is that on-line resizes of filesystems with a 1k blocksize will usually fail. The regression is that when a filesystem with 1k blocksize is stressed, the filesystem can get corrupted. On balance, on-line resizing failing is less of a disaster than corrupting the filesystem when its stressed. Fortunately, it's only an issue when the filesystem blocksize is less than the page size, which isn't the common case at least for the x86. There are patches queued up to address this, but they haven't hit mainline yet. Probably best to pull this from the stable tree for now. - Ted -- 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/
