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 in the whole volume. For more details, please check the commit log. Regards, Tao
