gfs2_dump_glock(9)

🌸 gfs2_dump_glock(9) — like, the Kernel API Manual page for gfs2_dump_glock 💅

okay bestie so this is gfs2_dump_glock(9) from the Kernel API Manual, and it does exactly one iconic little thing: it prints info about a glock. that's it. that's the whole vibe. let's get into it 🫶

---

✨ NAME ✨

gfs2_dump_glock — print information about a glock

like literally, that's her job. printing glock info. no notes. 👑

---

🦋 SYNOPSIS 🦋

void gfs2_dump_glock (struct seq_file *seq , struct gfs2_glock *gl ,
bool fsid );

she takes three things and returns nothing (void, my beloved lowkey-underrated return type) 💜

---

🎀 ARGUMENTS 🎀

• seq — The seq_file struct. this is where the output goes, bestie — it's the whole stage 🎭
• gl — the glock. the main character, fr fr 💫
• fsid — If true, also dump the file system id. yes, it's a bool. no, you can't be normal about it. 🙈

---

🌈 DESCRIPTION 🌈

so the file format is giving very specific, and here's how it works, no cap:

One line per object, and capital letters are used to indicate objects — memorize these, there will be a quiz:

• G = glock
• I = Inode
• R = rgrp
• H = holder

Glocks are not indented. everybody else? indented by a single space, and they follow the glock to which they are related. it's giving little ducklings following mama glock 🦆🦆

Fields are indicated by lower case letters followed by a colon and then the field value — except for strings, which are in [] so that it's possible to see if they are composed of spaces for example. string disclosure, we love to see it ✨

and the fields are:

• n = number (id of the object)
• f = flags
• t = type
• s = state
• r = refcount
• e = error
• p = pid

that's the whole legend. screenshot it. 🍓
