Hi I'm looking at the patch 8f50e358153dd68182c714626be4a90b64179cf4. The patch claims that dm-crypt can't deal with large bios - but I fixed this problem with dm-crypt a year before (see the patch 4e870e948fbabf62b78e8410f04c67703e7c816b). Was my fix for dm-crypt inefficient? Can you provide some test where dm-crypt fails with big bios? Should 8f50e358153dd68182c714626be4a90b64179cf4 be dropped? The variable ti->max_io_len is really split boundary (although it is incorrectly called len), so if we set it, se are splitting even small bios that cross this boundary.
