lsm_backing_file_alloc(9)

✨ lsm_backing_file_alloc(9) ✨

okay so bestie, you found the lsm_backing_file_alloc(9) page in the Kernel API Manual and like… it's short, but it's important, so let's go 💅

lsm_backing_file_alloc — allocate a composite backing file blob 🎀

int lsm_backing_file_alloc (struct file *backing_file );

like, yes, that semicolon-in-the-arg-list is exactly how it's written, don't come for me 💀

backing_file — the backing file 🫶 that's it. that's the whole argument. she's a struct file * and she's the backing file, periodt.

So what does she do? She allocates the backing file blob — for all the modules 👑 like, the composite one, everybody gets a slot, no cap.

Returns 0, or -ENOMEM if memory can't be allocated 😭 (memory said no, and honestly? relatable).

ngl, the -ENOMEM path is the only drama here: either you get your 0 and you're slaying, or the allocator ghosted you 🙈

okay this list is long long — like she tagged every single friend in the group chat 💀 but it's all here, every single one, so vibe check passed ✨

and that's the whole page bestie, you ate that 🫶 go forth and allocate 💖

okayyy signing off!! this one came from the source ./security, dated October 2026 — love that for her, iconic, no notes 💖✨
