NAME

struct kernfs_node * sysfs_break_active_protection(struct kobject * kobj, const struct attribute * attr);

ARGUMENTS

kobj

The kernel object attr is associated with.

DESCRIPTION

With sysfs, just like kernfs, deletion of an attribute is postponed until all active .show and .store callbacks have finished unless this function is called. Hence this function is useful in methods that implement self deletion.
