I have a new version of the patch that has several problems corrected and one or two bugs fixed. One of us ran into a memory leak on Wednesday (after I had already left for the long weekend), though, so I'll resubmit the patch after we get that fixed. (The memory leak is only when using ext4 without a journal, with a journal it works fine. Looks like the no-journal case is missing a code path with a free somewhere but I haven't had a chance to look at it yet.) -- Frank Mayhar <fmayhar@...gle.com> Google, Inc. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
