dm: sysfs add empty release function to avoid debug warning (d2bb7df8) · Commits · 戴 / test

This patch just removes an unnecessary warning: kobject: 'dm': does not have a release() function, it is broken and must be fixed. The kobject is embedded in mapped device struct, so code does not need to release memory explicitly here. Cc: stable@kernel.org Signed-off-by:
