user_exp_rcv_invalid(9)

🌸 NAME 🌸

okay so bestie, this is user_exp_rcv_invalid(9) from the Kernel API Manual, and it does exactly what it says on the tin: invalidate the given tid rcv list ✨

🎀 SYNOPSIS 🎀

int user_exp_rcv_invalid (struct hfi1_filedata *fd , unsigned long arg ,
u32 len );

💅 ARGUMENTS 💅

• fd — file data of the current driver instance, aka the vibe check for which driver context we're in 🫶
• arg — ioctl argument for user space information, carrying the user-space details through 😌
• len — length of data structure associated with ioctl command, because bestie we gotta know how much data we're dealing with 💖

✨ DESCRIPTION ✨

This is a wrapper, no cap: it validates ioctl information before doing _rcv_invalid. Think of it as the little pre-flight check with main character energy — it makes sure the ioctl info is valid first, then the real _rcv_invalid work happens 🔥
