PROBE::NFS.FOP.L(3stap)

πŸ’– probe::nfs.fop.llseek β€” from the Network File Storage Tapsets crew (that's PROBE::NFS.FOP.L(3stap) bestie, section 3stap of the SystemTap tapset reference) πŸ¦‹

okay so. listen. this is the manual page for a SystemTap probe and it's giving niche but iconic. no cap.


✨ NAME ✨

probe::nfs.fop.llseek β€” literally the NFS client llseek operation, that's it, that's the whole vibe 🌸


πŸŽ€ SYNOPSIS πŸŽ€

probe nfs.fop.llseek {}

yep that's the whole thing. no arguments, no fuss, just a probe sitting there with main character energy πŸ’…


πŸ‘‘ VALUES πŸ‘‘

these are the variables you get to peek at when the probe fires. every single one, we're listing them all, periodt:

  • offset β€” the offset of the file, aka where it's about to be repositioned to 🫢
  • dev β€” the device identifier. which device? this device, bestie πŸ“
  • ino β€” the inode number. very demure, very identifier 🌈
  • whence β€” the position to seek from. where are we seeking from, queen πŸ‘‘
  • whence_str β€” the symbolic string representation of the position to seek from, aka whence but it speaks in words, slay ✨
ngl, whence vs whence_str is the classic number-vs-name duo and honestly? obsessed 😭

πŸ¦‹ SEE ALSO πŸ¦‹

  • tapset::nfs(3stap) β€” go read the whole NFS tapset family, it's a whole ecosystem fr fr 🧚

and that's the page!! big love to the SystemTap Tapset Reference, Version September 2026, for making this little probe possible πŸ’œ stay curious, read your tapsets, and remember: the offset is always being repositioned somewhere πŸ’«
