Correct. A v1 record carrying a 16-byte BLK_TA_REMAP PDU is 64 bytes, the size of a v2 record, and nothing else in the entry tells them apart. v2 drops the size test and depends on Adriano Cordova's "blktrace: always record ftrace events as blk_io_trace2" instead: https://lore.kernel.org/all/[email protected]/
