💖 srp_fr_pool_put(9) 💖

okay so bestie, this page is from the Kernel API Manual, and it’s literally about putting an FR descriptor back in the free list. group-chat recap time 🫶

🌸 NAME 🌸

srp_fr_pool_put — put an FR descriptor back in the free list ✨

✨ SYNOPSIS ✨

void srp_fr_pool_put (struct srp_fr_pool *pool , struct srp_fr_desc **desc , int n );

that’s the signature, no cap 💅

🎀 ARGUMENTS 🎀

• pool — the pool the descriptor was allocated from. it’s giving “where did this come from?” energy.
• desc — pointer to an array of fast registration descriptor pointers. yes, pointer-to-an-array-of-pointers, iconic behavior, stay with me 🦋
• n — number of descriptors to put back. basically the count, periodt.

🚨 NOTE 🚨

okay so this is the serious bit: the caller must already have queued an invalidation request for desc->mr->rkey before calling this function. do not skip this, bestie, fr fr 😭
