Hi Ted, changelog from v1 to v2: 1. integrated comments form Lukas. 2. add another trivial fix reported by Andreas. Patch 1/5 is a fix for the 'len' overflow. As we have decided that we don't adjust start to s_first_data_block, this patch is still needed. Patch 2/5 is a speedup for trim in one group. Patch 3/5 adds trace points for the functions used in FITRIM. Patch 4/5 is a speedup for trim for the whole volume. Patch 5/5 is a trivial fix for the comment of ext4_trim_all_free. Thanks, Tao -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
