Question about BIGALLOC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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?
