# [DESCRIPTION](#DESCRIPTION)

Prefer modern scsi\_execute\_cmd, but keep \_\_scsi\_execute / scsi\_execute so RHEL8-era 4.18 still resolves (scsi\_execute was often only a macro around \_\_scsi\_execute). 994724e6b3f0 introduced scsi\_execute\_cmd (opf / ml\_retries instead of data\_direction / retries).
