[PATCH] md: Handle overflow of mdu_array_info_t->size better
mdu_array_info_t->size is 'int', which isn't big enough for the size (in KB of
each component in) some arrays.
So rather than a random overflow, set size to -1 when it cannot be set
correctly.
To update aspect on an array, userspace will sometimes:
get_array_info
change one field
set_array_info
in this case, we don't want the '-1' in 'size' to change to size, or look like
a size change at all. So test for that in update_array_info.
