#     powerpc/powernv/dump: Handle multiple writes to ack attribute
#     
#     Even though we use self removing sysfs helper, we still need
#     to make sure we do the final kobject delete conditionally.
#     sysfs_remove_file_self() will handle parallel calls to remove
#     the sysfs attribute file and returns true only in the caller
#     that removed the attribute file. The other parallel callers
#     are returned false. Do the final kobject delete checking
#     the return value of sysfs_remove_file_self().
