svc_rdma_post_send_err(9)

💅 NAME

Bestie, meet svc_rdma_post_send_err(9) from the Kernel API Manual — this icon is literally here to handle ib_post_send failure. That’s the assignment, no cap 💖✨

🌸 SYNOPSIS 🌸

The signature is giving exactly this, bestie:

       int svc_rdma_post_send_err (struct svcxprt_rdma *rdma , const struct
       rpc_rdma_cid *cid , const struct ib_send_wr *bad_wr , const struct
       ib_send_wr *first_wr , int sqecount , int ret );

🎀 ARGUMENTS 🎀

• rdma — controlling transport 👑
• cid — completion ID for tracing 🔍
• bad_wr — first WR that was not posted 😭
• first_wr — first WR in the chain 🔗
• sqecount — number of SQ entries that were reserved 🧚
• ret — error code from ib_post_send 💀

🦋 DESCRIPTION 🦋

Return values, bestie — this is the whole plot:

• 0 — At least one WR was posted; a completion handles cleanup ✨
• -ENOTCONN — No WRs were posted; SQ slots are released 🫶
