That is, block_acct_failed/done without previous block_acct_start; in that case, cookie probably holds values from previous operation. (Note: it might also be uninitialized holding garbage value and there is still "< BLOCK_MAX_IOTYPE" assertion for that. So block_acct_failed/done without previous block_acct_start should be used with caution.) Currently this is particularly useful in ide code where it's hard to keep track whether the request started accounting or not. For example, trim requests do the accounting separately.

The difference is that we don't call scsi_disk_req_check_error() before the 1st discard iteration anymore. That function also checks if the request is cancelled, however it shouldn't get canceled until it yields in blk_aio() functions anyway. Same approach is already used for emulate_write_same.
