md: mark some attributes as pre-alloc Since __ATTR_PREALLOC was introduced in v3.19-rc1~78^2~18 it can now be used by md. This ensure that writing to these sysfs attributes will never block due to a memory allocation. Such blocking could become a deadlock if mdmon is trying to reconfigure an array after a failure prior to re-enabling writes. Signed-off-by: NeilBrown <neilb@suse.de>
