✨ nfsd_setattr(9) ✨

okay so bestie, this is a page from the Kernel API Manual and it's literally all about nfsd_setattr — the little icon that sets various file attributes 💅 like it's giving file-glow-up energy and we're obsessed.

🌸 NAME 🌸

nfsd_setattr — set various file attributes. that's it, that's the vibe 🎀

🦋 SYNOPSIS 🦋

__be32 nfsd_setattr (struct svc_rqst *rqstp , struct svc_fh *fhp ,
       struct nfsd_attrs *attr , const struct timespec64 *guardtime );

no cap, that's the whole signature. copy it exactly, bestie, don't be out here renaming things 😭

💖 ARGUMENTS 💖

  • rqstp — the controlling RPC transaction. like, the main character of this whole call 🫶
  • fhp — the filehandle of the target. it's pointing at the file we're about to give a whole new look ✨
  • attr — the attributes to set. the actual lewk we're serving 💅
  • guardtime — do not act if ctime.tv_sec does not match this timestamp. fr fr, it's a vibe check: if the timestamp doesn't match, we simply do not proceed 🙈

🧚 DESCRIPTION 🧚

so this call may adjust the contents of attr — and lowkey that's important, bestie. in particular, this call may change the bits in the na_iattr.ia_valid field. like it's editing its own homework, but make it kernel 🎀

it returns nfs_ok on success. otherwise, an NFS status code is returned. either way, the caller must release fhp by calling fh_put. no exceptions, no "I'll do it later", periodt. 🫶

💀 reminder: caller must release fhp by calling fh_put in either case — success or not, bestie. don't leave that filehandle hanging, it's not cute.

🌈 SEE ALSO 🌈
