unregister_filesystem(9)

💫 unregister_filesystem — a Kernel API Manual moment 💫

okay bestie, so we're in the unregister_filesystem(9) page of the Kernel API Manual and it's literally about saying bye to a filesystem 👋✨

🌸 NAME 🌸

unregister_filesystem — unregister a file system

✨ SYNOPSIS ✨

int unregister_filesystem (struct file_system_type *fs );

🎀 ARGUMENTS 🎀

• fs — the filesystem you wanna unregister, babes 💅

🦋 DESCRIPTION 🦋

okay so picture this: you've got a file system that was previously successfully registered with the kernel, and now you need it gone. that's the whole gig 🫶 this function removes it.

and like, if the file system isn't found? you get an error back. no cap 😭 but if everything goes off without a hitch, you get zero back on a success. slay ✨

also highkey important: once this function has returned, the struct file_system_type structure may be freed or reused. so like, it's giving "we're done here, do what you want with it now" 💀

🌈 SEE ALSO 🌈

• Kernel file ./fs/filesystems.c
• register_filesystem(9)

and that's the vibe check, bestie 💖 this lil gem lives in ./fs and the page is dated October 2026 — handwritten by the kernel girlies, obviously. unregister_filesystem(9) out. periodt 🧚⭐
