Before someone asks, it is valid to declare a pointer as 'read mostly', even if the data pointed by the pointer is heavily modified. hash table pointers and kmem_cache pointers are setup at boot time, so they are perfect candidates to 'read_mostly' section. Same apply for 'struct vfsmount *'


Yes... why wouldn't it be if the variable is only written to once? This
is _exactly_ what __read_mostly section is for, isn't it?

Patch looks good though.
