🎀 Members

So like, here's the whole cast of this struct — every single one of them matters, no skipping 🙈

• req — the CDB command fields, exactly as described in the CMIS standard. Iconic, standards-compliant, we love to see it 💖
• max_duration — the maximum duration time for command completion, in msec. It's giving "how long are we willing to wait for this to finish" energy ⏳
• msleep_pre_rpl — the waiting time before checking the reply, in msec. Yes bestie, we nap before we peek 😴
• read_write_len_ext — the allowable additional number of byte octets to the LPL in a READ or a WRITE command. Lowkey a mouthful but it's important 🫶
• rpl_exp_len — expected reply length in bytes. Set your expectations, queen 👑
• flags — validation flags for CDB commands. The vibe check flags, fr fr 🚩
• err_msg — the error message to be sent to user space. When things go wrong, we tell the humans 💀
