💅 nfs_inode_reclaim_delegation — kernel API manual, bestie edition

okay so this is a page from the Kernel API Manual (yes, the kernel has lore, and yes, it's giving documentation era). Today's main character is nfs_inode_reclaim_delegation(9) — say that five times fast, I dare you 😭

✨ NAME ✨

nfs_inode_reclaim_delegation — the function that handles a delegation reclaim request. That's it, that's the vibe. 🫶

🌸 SYNOPSIS 🌸

void nfs_inode_reclaim_delegation (struct inode *inode , const struct
       cred *cred , fmode_t type , const nfs4_stateid *stateid , unsigned long
       pagemod_limit , u32 deleg_type );

no cap, that's the whole signature — copy it exactly if you're typing it out, she's picky about her pointers and her spacing 💀

🦋 ARGUMENTS 🦋

okay so this function takes six things and every single one of them matters, so let's go through them one by one like we're doing a vibe check on each parameter 👑

  • inode — the inode we're processing. the literal subject of the whole operation. main character energy, honestly 👑
  • cred — the credential to use for the request. like, who's allowed to be doing this. bring your ID bestie 🪪
  • type — the delegation type. it's an fmode_t, so it's mode-flavored. iconic ✨
  • stateid — the delegation stateid. a const nfs4_stateid *, because we're looking, not touching 🙈
  • pagemod_limit — the write delegation "space_limit". yes, the original puts space_limit in quotes, so we keep it in quotes, periodt 💅
  • deleg_type — the raw delegation type. a u32, and importantly raw, so don't go confusing it with the processed type up there — they are not the same girl, don't merge them 😤
lowkey the biggest flex here is that type and deleg_type are two separate arguments and you absolutely must not swap them. iykyk 🧚

🎀 SEE ALSO 🎀

the kernel file this lives in is ./fs/nfs/delegation.c — that's the address, that's the whole neighborhood 🏡

and now, the delegation cinematic universe, in the exact order the page gives it. buckle up bestie, it's a long one 🌈

like… twenty-four cross-references. twenty-four. she ate and left absolutely no crumbs 🔥🍓

and that's the page!! 🎀 source is ./fs/nfs, dated October 2026, and the whole thing is filed under nfs_inode_re...m_delegation(9) — yes the title is abbreviated with literal dots, no that's not a typo on my end, that's just how she's listed 💜 bye bestie, go reclaim some delegations responsibly 💅✨
