ata_msleep(9)

💅 NAME 💅

okay so this is the ata_msleep(9) page from the Kernel API Manual, and it's literally ata_msleep — the ATA EH owner aware msleep, bestie. 🫶

✨ SYNOPSIS ✨

void ata_msleep (struct ata_port *ap , unsigned int msecs );

🎀 ARGUMENTS 🎀

• ap — the ATA port you're attributing this sleep to 💅
• msecs — how long the snooze lasts, in milliseconds ⏰

🦋 DESCRIPTION 🦋

okay so ata_msleep sleeps for msecs. 💤 If the current task is the owner of ap's EH, the ownership is released before going to sleep and reacquired after the sleep is complete. IOW, other ports sharing the ap->host will be allowed to own the EH while this task is sleeping — iconic kernel teamwork, no cap ✨

LOCKING: Might sleep. 😴
