Subject: Unusual code in mballoc.c.
Date: Sun, 28 Sep 2008 11:56:12 +1000	[thread overview]
Message-ID: <200809281156.12688.rusty@rustcorp.com.au> (raw)

Hi all,

   A grep lead me to fs/ext4/mballoc.c:

Line 2551:
	for (i = 0; i < nr_cpu_ids; i++) {

This is more normally "for_each_possible_cpu(i)".

Line 4097:
	ac->ac_lg = &sbi->s_locality_groups[get_cpu()];
	put_cpu();

This is presumably someone suppressing a warning.   It should be:
	ac->ac_lg = &sbi->s_locality_groups[raw_smp_processor_id()];

Thanks,
Rusty.
