> xfs: avoid unnecessary runtime sibling pointer endian conversions
>
> From: Dave Chinner <dchinner@...hat.com>
>
> Commit dc04db2aa7c9 has caused a small aim7 regression, showing a
> small increase in CPU usage in __xfs_btree_check_sblock() as a
> result of the extra checking.
>
> This is likely due to the endian conversion of the sibling poitners
> being unconditional instead of relying on the compiler to endian
> convert the NULL pointer at compile time and avoiding the runtime
> conversion for this common case.
>
> Rework the checks so that endian conversion of the sibling pointers
> is only done if they are not null as the original code did.
>
> Fixes: dc04db2aa7c9 ("xfs: detect self referencing btree sibling pointers")
> Reported-by: kernel test robot <oliver.sang@...el.com>
> Signed-off-by: Dave Chinner <dchinner@...hat.com>
