ENUM MMC_DRV_OP(9)

✨ enum mmc_drv_op ✨

okay bestie, so this is a page from the Kernel API Manual and it's literally just a little enum that lists out the operations you can shove into an mmc_queue_req 💅 like it's the menu at your fave café but for MMC driver ops, iykyk.

👑 CONSTANTS 👑

okay so here's the whole squad, no skips, every single one gets their moment ⭐

• MMC_DRV_OP_IOCTL — the plain, classic ioctl operation. the main character of the group honestly 🫶
• MMC_DRV_OP_IOCTL_RPMB — the ioctl operation that's all about RPMB. RPMB-oriented, if you will 💖
• MMC_DRV_OP_BOOT_WP — write protects the boot partitions. protective queen behavior 🔥
• MMC_DRV_OP_GET_CARD_STATUS — goes and gets the card status. a little fetch quest 🌈
• MMC_DRV_OP_GET_EXT_CSD — grabs the EXT CSD from an eMMC card. iconic eMMC-specific moment 👑

lowkey that's the whole page 💀 no hidden lore, no gotchas, just five enum values doing their thing. still slayed tho 💅
