Subject: [PATCH 0/4 RESEND]  ext4 trim bug fixes and improvement.

Hi Ted,
	I just found these patches haven't been included yet, so resend them
and hope they can be included in 3.1.

    Patch 1/4 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 2/4 is a speedup for trim in one group.
    Patch 3/4 adds trace points for the functions used in FITRIM.
    Patch 4/4 is a speedup for trim for the whole volume.

Thanks,
Tao
