💖 NAME 💖

okay so this is the Kernel API Manual page for pmcraid_allocate_hcams(9), and it is literally the function that allocates HCAM buffers. bestie, the name says it all: pmcraid_allocate_hcams — allocates HCAM buffers. ✨

📜 SYNOPSIS 📜

int pmcraid_allocate_hcams (struct pmcraid_instance *pinstance );

🎀 ARGUMENTS 🎀

• pinstance — pointer to per adapter instance structure. yes bestie, it's the per-adapter instance pointer, no cap 💅

🌸 DESCRIPTION 🌸

Return Value: 0 in case of successful allocation, non-zero otherwise.

so vibe check: 0 means the allocation succeeded, and anything non-zero means it did not. that's the whole tea ☕
