nfs42_proc_offload_status(9)

🌸 NAME 🌸 (aka nfs42_proc_offload_status(9) in the Kernel API Manual)

okay so bestie, nfs42_proc_offload_status is literally the function that polls completion status of an async copy operation. no cap, that's the whole main character energy of this page 🦋✨

✨ SYNOPSIS ✨

int nfs42_proc_offload_status (struct file *dst , nfs4_stateid *stateid , u64 *copied );

🎀 ARGUMENTS 🎀

• dst — handle of file being copied into 🫶
• stateid — copy stateid (from async COPY result) 💅
• copied — OUT: number of bytes copied so far 👑

💖 DESCRIPTION 💖

the return values are doing the most, and I'm obsessed with how specific they are:

• 0 — Server returned an NFS4_OK completion status ✅
• -EINPROGRESS — Server returned no completion status ⏳
• -EREMOTEIO — Server returned an error completion status 💀
• -EBADF — Server did not recognize the copy stateid 🙈
• -EOPNOTSUPP — Server does not support OFFLOAD_STATUS 🚫
• -ERESTARTSYS — Wait interrupted by signal 😭

Other negative errnos indicate the client could not complete the request. periodt, that's the vibe check fr fr.
