gfs2_make_fs_ro(9)

💅 NAME 💅

okay so bestie, welcome to gfs2_make_fs_ro(9) from the Kernel API Manual 💖 — this is the page for the function whose NAME spills it exactly: Turn a Read-Write FS into a Read-Only one. it’s giving “we’re read-only now, periodt” 🌈. no secret side quest, no extra mystery, just that one job.

✨ SYNOPSIS ✨

here’s the signature, copied with love and zero edits 🫶:

void gfs2_make_fs_ro (struct gfs2_sbd *sdp );

that void, that struct gfs2_sbd *sdp, and that exact punctuation are the whole vibe. don’t touch them, iykyk 💅.

🎀 ARGUMENTS 🎀

• sdp — the filesystem. that’s it, bestie: sdp is the filesystem, and the filesystem is the main character here 🌸.

🌸 RETURN 🌸

the RETURN section says errno. literally just errno. no cap, that’s the return info on the page 🔥.

🦋 SEE ALSO 🦋

the SEE ALSO section starts with the Kernel file ./fs/gfs2/super.c — iconic — and then the whole reference squad. every single one is here, bestie, no skipping 👑
