kmemleak_vmalloc(9)

💖 kmemleak_vmalloc — the kernel API manual, but make it make sense 💖

okay so bestie, this one's a kernel API page from the 9 section (that's the "kernel internals" shelf, iykyk) 🧚✨

✨ NAME ✨

kmemleak_vmalloc — the little function that registers a freshly vmalloc'ed object with kmemleak 🎀

🦋 SYNOPSIS 🦋

void __ref kmemleak_vmalloc (const struct vm_struct *area , size_t size
, gfp_t gfp );

🌸 ARGUMENTS 🌸

• area — pointer to vm_struct. it's the struct, bestie, hand it over 🫶
• size — size of the object. yes, the actual size, no vibes-based guessing 💅
• gfp — the __vmalloc flags used for kmemleak's own internal memory allocations. it's giving "budget allocation energy" but for kmemleak itself ✨

💜 DESCRIPTION 💜

so here's the tea ☕: this function gets called from the vmalloc kernel allocator whenever a brand-new object (memory block) gets allocated. that's it. that's the whole job. it registers the new thing so kmemleak knows what's up 👑

no cap, it's the main character of the vmalloc allocation moment 🌈
