Remove array_size() calls and replace vmalloc() with vmalloc_array() in
ubifs_create_dflt_lpt()/lpt_init_rd()/lpt_init_wr(). vmalloc_array() is
optimized better, resulting in less instructions being used [1].

Makes sense. Do you want me to carry this through the ubifs tree or do you have
a distinct tree with all your vmalloc_array() patches?
Please carry this through the ubifs tree. Thanks for handling it!
