Subject: logbufs default value

Hi List!
>From linux-2.6.39/Documentation/filesystems/xfs.txt:
logbufs=value
Set the number of in-memory log buffers. Valid numbers range
from 2-8 inclusive.
The default value is 8 buffers for filesystems with a
blocksize of 64KiB, 4 buffers for filesystems with a blocksize
of 32KiB, 3 buffers for filesystems with a blocksize of 16KiB
and 2 buffers for all other configurations. Increasing the
number of buffers may increase performance on some workloads
at the cost of the memory used for the additional log buffers
and their associated control structures.
Is this still valid? I thought that newer kernels would always use 8 as
default?
tia,
Michael
