Hi, Ted I am doing some test of BIGALLOC using "next" branch of e2fsprogs and kernel (3.0) with 23 bigalloc-patches. Everything seems to work, but I have a question: the "ee_len" of "struct ext4_extent" is used to indicate block numbers not cluster, an ext4_extent in 4K-block-size filesystem can only hold 128MB space at most even with BIGALLOC feature enabled, so we don't have any benefit from this for a file with large number of blocks. Is this the design behavior or you will change it in the next version? -- -- Best Regard Robin Dong -- 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
