gfs2_thaw_super(9)

💖 gfs2_thaw_super(9) 💖

okay bestie, so this is a page from the Kernel API Manual — yes, that gfs2_thaw_super(9), the one and only ✨

Like, the whole personality of this function is in one line: reallow writes to the filesystem. That's it. That's the vibe. It thaws the superblock so writes can happen again 🧊➡️🔥

✨ SYNOPSIS ✨

int gfs2_thaw_super (struct super_block *sb , enum freeze_holder who ,
const void *freeze_owner );

literally three args and a dream, no cap 🫶

🎀 ARGUMENTS 🎀

• sb — the VFS structure for the filesystem, like the main character's ID card 💅
• who — the freeze flags, telling everyone who is doing the freezing iykyk 🌸
• freeze_owner — owner of the freeze, the one holding the aux cord on this whole operation 🎧
