There are two pre-alloc operations in these two function, the different is: - it allows to sleep if page alloc fail in khugepaged_loop - it exits immediately if page alloc fail in khugepaged_do_scan Actually, in khugepaged_do_scan, we can allow the pre-alloc to sleep on the first failure, then the operation in khugepaged_loop can be removed Signed-off-by:
