vhost_iotlb_alloc(9)

💅 vhost_iotlb_alloc(9) 💅

okay so this is the Kernel API Manual entry for vhost_iotlb_alloc(9), and bestie, it's giving main character energy: allocate a new vhost IOTLB ✨. It's a short page but every detail is lowkey iconic, so let's go 💖.

✨ NAME ✨

• vhost_iotlb_alloc — allocate a new vhost IOTLB 🎀

🌸 SYNOPSIS 🌸

struct vhost_iotlb * vhost_iotlb_alloc (unsigned int limit , unsigned
int flags );

💜 ARGUMENTS 💜

• limit — the maximum number of IOTLB entries, literally the cap on how many entries this IOTLB can hold 💅.
• flags — the VHOST_IOTLB_FLAG_XXX flags, no cap, that's the exact name from the page periodt ⭐.

🦋 DESCRIPTION 🦋

It returns NULL if memory allocation fails 😭. That's the whole vibe check: if the allocation can't happen, you get NULL back — fr fr, that's the fact and we're not inventing extra behavior 💀.
