ata_platform_remove_one(9)
π ata_platform_remove_one(9) β like, the platform-layer callback for when a device β¨leavesβ¨
okay so real talk, bestie: this one's a page out of the Kernel API Manual, and it's short but it matters β it's the little hook that tells libata "hey girl, that device is gone, wrap it up π".
β¨ NAME β¨
ata_platform_remove_one β the platform layer callback for device removal π«Ά
πΈ SYNOPSIS πΈ
void ata_platform_remove_one (struct platform_device *pdev );
π¦ ARGUMENTS π¦
pdevβ the platform device that was removed. yeah, that one. it's gone now π
π DESCRIPTION π
So the platform layer uses this hook to tell libata that a hot-unplug or a module unload event just happened π. In response, it detaches all ports. That's the whole job.
Now, before you panic about cleanup β resource release is not your problem here, because it's handled via devres β¨. so clean, so iconic, no manual teardown arc.
LOCKING: inherited from the platform layer β and heads up, it may sleep π΄. so don't go calling it from somewhere spicy, iykyk.
