dca_common_get_tag(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual page for dca_common_get_tag(9) — yes, the manual name is folded in right here, and we are gonna make it make sense 💅.

• dca_common_get_tag — return the dca tag (serves both new and old api). that's the assignment, no cap ✨
• @dev — the device that wants dca service 🫶
• @cpu — the cpuid as returned by get_cpu() 🌸

✨ SYNOPSIS ✨

the signature is giving short-but-iconic, lowkey:

u8 dca_common_get_tag (struct device *dev , int cpu );

🎀 ARGUMENTS 🎀

bestie, the docs are out here being mysterious on purpose 😭:

• dev — -- undescribed -- 🙈 (the NAME line does say it's the device that wants dca service)
• cpu — -- undescribed -- 💀 (and the NAME line says it's the cpuid as returned by get_cpu())

yes, both argument descriptions are literally -- undescribed -- in the original. iykyk 🫶
