XSDFEC_SET_ORDER(9)

💅 XSDFEC_SET_ORDER

okay so welcome to the Kernel API Manual, bestie — today’s main character is XSDFEC_SET_ORDER(9), and the short version is literally Parameters. No cap. 💖

📋 Parameters

• struct unsigned long * — a pointer to the unsigned long that contains a value from enum xsdfec_order. That’s the whole parameter list, and it ate. 💅

💬 Description

okay so this is the ioctl that sets order, if order of blocks can change from input to output. That “if” is doing a lot of work, so don’t skip it. 🫶

⚠️ This can only be used when the driver is in the XSDFEC_STOPPED state. Like, that’s the vibe check — not stopped? not today. 😭
