frwr_reset(9)

💖 NAME 💖

okay bestie, welcome to frwr_reset(9) from the Kernel API Manual — manual name folded in right here like a lil name tag 🫶. This function is frwr_reset, and its whole thing is: place MRs back on @req's free list. slay. ✨

🌸 SYNOPSIS 🌸

the vibe check:

void frwr_reset (struct rpcrdma_req *req );

🎀 ARGUMENTS 🎀

• req — the request to reset, bestie. that’s the one 💅

💅 DESCRIPTION 💅

okay so this one is used after a failed marshal. for FRWR, that means the MRs don’t have to be fully released and recreated. iconic cleanup behavior, honestly 🧚

NB: this is safe only as long as none of req’s MRs are involved with an ongoing asynchronous FAST_REG or LOCAL_INV Work Request. like, do not ignore this, fr fr 😭
