Slab: Fix memory leak in fallback_alloc()
The zonelist patches caused the loop that checks for available objects in permitted zones to not terminate immediately. One object per zone per allocation may be allocated and then abandoned. Break the loop when we have successfully allocated one object. Signed-off-by: Christoph Lameter <clameter@sgi.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
