With the coherency fix commit reverted (as mentioned in the bug report)
I get:

# cryptsetup benchmark --cipher aes-cbc
# Tests are approximate using memory only (no storage IO).
#  Algorithm | Key |  Encryption |  Decryption
     aes-cbc   256b    65.8 MiB/s    67.1 MiB/s

so not that different from before.  Run more than 10 times without issue.
