gfs2_unpin(9)

💖 NAME 💖

gfs2_unpin — unpin a buffer, bestie. that's it, that's the whole vibe 🦋

this lil guy lives in section 9 of the Kernel API Manual, so yes it's a kernel-space moment, not your average userland slay 💅

---

✨ SYNOPSIS ✨

void gfs2_unpin (struct gfs2_sbd *sdp , struct buffer_head *bh , struct
gfs2_trans *tr );

okay so it returns void, meaning it gives you nothing back, no cap, no return value, just vibes and side effects 🫶

---

🎀 ARGUMENTS 🎀

• sdp — the filesystem the buffer belongs to. like, whose buffer is this? this one. it's giving "main character filesystem" energy 👑
• bh — The buffer to unpin. the actual star of the show, the one getting unpinned, periodt ✨
• tr — The system transaction being flushed. the transaction that's mid-flush, lowkey carrying the whole plot 🌸

ngl, if you were looking for flags, options, environment variables, exit statuses or signals… there are literally none here 🙈 this page is short and sweet and we love that for it. no warnings, no bugs section, no authors, no copyright, no license text — just the buffer, the filesystem, and the transaction. slay 💅
