nfs41_check_open_stateid(9)

💅 nfs41_check_open_stateid(9) — the kernel API manual, but make it make sense ✨

okay so bestie, welcome to the nfs41_check_open_stateid page from the Kernel API Manual, and honestly? it's a tiny one but she's important. we're talking NFSv4 stateid recovery, and this function is the one that decides whether an open stateid can finally be freed. lowkey iconic behavior. 🫶

🦋 NAME 🦋

nfs41_check_open_stateid — possibly free an open stateid ✨

like, possibly. she's not out here freeing things all willy-nilly. the vibe is "check first, free later." 🔥

---

🌸 SYNOPSIS 🌸

int nfs41_check_open_stateid (struct nfs4_state *state );

that's it. one function, one argument, one int coming back at you. clean. minimal. main character energy. 👑

---

🎀 ARGUMENTS 🎀

• state — the NFSv4 state for an inode. that's your whole input, bestie, so handle her with care. 🍓

---

💖 DESCRIPTION 💖

okay so here's the tea: this function returns NFS_OK if recovery for this stateid is now finished. that's the good ending, the slay ending, the "we can pack up and go home" ending. 🌈

otherwise? you get a negative NFS4ERR value back. not NFS_OK, not zero, not a friendly little wave — a negative NFS4ERR value. so if you were hoping for a happy return, do a vibe check on that stateid first. 😭

and remember what the NAME said: possibly free an open stateid. the freeing is not guaranteed, it's contingent. no cap. 💀
