avoid unnecessary runtime sibling pointer endian conversions
Dave Chinner <dchinner@xxxxxxxxxx>
dc04db2aa7c9 has caused a small aim7 regression, showing a
increase in CPU usage in __xfs_btree_check_sblock() as a
of the extra checking.
is likely due to the endian conversion of the sibling poitners
unconditional instead of relying on the compiler to endian
the NULL pointer at compile time and avoiding the runtime
for this common case.
the checks so that endian conversion of the sibling pointers
done if they are not null as the original code did.
