Subject: sys_swapon: do not depend on "type" after allocation
X-Git-Tag: v2.6.39-rc1~311

sys_swapon: do not depend on "type" after allocation

Within sys_swapon, after the swap_info entry has been allocated, we
always have type == p->type and swap_info[type] == p. Use this fact to
reduce the dependency on the "type" local variable within the function,
as a preparation to move the allocation of the swap_info entry to a
separate function.
