✨ nfs4_preprocess_seqid_op(9) ✨

okay so bestie, this one lives in the Kernel API Manual and it's literally the girl who finds your ol_stateid and gets it all prepped for a seqid-morphing op. no cap, she's a whole vibe 💅

🌸 NAME 🌸

nfs4_preprocess_seqid_op — find and prep an ol_stateid for a seqid-morphing op 🎀

🦋 SYNOPSIS 🦋

__be32 nfs4_preprocess_seqid_op (struct nfsd4_compound_state *cstate ,
u32 seqid , stateid_t *stateid , unsigned short typemask ,
unsigned short statusmask , struct nfs4_ol_stateid **stpp ,
struct nfsd_net *nn
);

like yes she takes seven args, she's high-maintenance, she's iconic 👑

💖 ARGUMENTS 💖

  • cstate — compound state 🫶 (the original page calls it "compund state", which is honestly so real of it)
  • seqid — the seqid, and it's provided by client — not us, never us 🙈
  • stateid — the stateid, also provided by client 🍓
  • typemask — mask of allowable types for this operation ✨
  • statusmask — mask of allowed states: 0 or STID_CLOSED 🔥
  • stpp — return pointer for the stateid found 💫 like here's where the find goes
  • nn — net namespace for request 🌈

👑 DESCRIPTION 👑

so here's the tea ☕ Given a stateid+seqid from a client, she looks up an nfs4_ol_stateid and returns it in stpp. that's the whole job and she ate 💅

and on an nfs_ok return — listen — the returned stateid will have its st_mutex locked 🔒 like she hands it to you already holding the lock, that's the deal, don't forget to deal with it bestie 😭

🧚 SEE ALSO 🧚

Kernel file ./fs/nfsd/nfs4state.c — and the whole group chat is here, fr fr:
