| |
I noticed the following issue in the code:
in drivers/ata/libata-acpi.c:
static void ata_acpi_handle_hotplug(struct ata_port *ap, struct ata_device *dev, u32 event) { ... spin_lock_irqsave(ap->lock, flags); ...
if (dev) { if (dev->sdev) kobj = &dev->sdev->sdev_gendev.kobj; } else kobj = &ap->dev->kobj;
if (kobj) { sprintf(event_string, "BAY_EVENT=%d", event); kobject_uevent_env(kobj, KOBJ_CHANGE, envp); }
spin_unlock_irqrestore(ap->lock, flags); ... }
and kobject_uevent_env() calls kzalloc(..., GFP_KERNEL);
