💅 NAME 💅

irdma_del_memlist — deleting pbl list entries for CQ/QP ✨

okay so this is a irdma_del_memlist(9) situation, it lives in the Kernel API Manual, and honestly? it's giving cleanup era. bestie, this bad boy is all about deleting pbl list entries for CQ/QP and nothing else. no cap, that's the whole vibe.

🌸 SYNOPSIS 🌸

bool irdma_del_memlist (struct irdma_mr *iwmr , struct irdma_ucontext
*ucontext );

like literally just hand it those two things and it's off to do its thing 💖

🎀 ARGUMENTS 🎀

  • iwmr — the iwmr holding IB's user page addresses 🦋 so like, the memory registration we're dealing with.
  • ucontext — ptr to user context. yep, a pointer. to the user context. that's her 👑

⭐ RETURN ⭐

Returns True if the MR is currently in-use by a QP/CQ/SRQ ring. that's it, that's the whole answer, True means somebody's still using it, iykyk 🔥

lowkey important: this is a bool return, so don't go expecting an int, bestie 💀
