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.
