# This must be adjusted manually to the value of HZ in the running kernel
# on 2.4, until the XFS people change their 2.4 external interfaces to work in
# centisecs. This can be automated, but it's a work in progress that still needs
# some fixes. On 2.6 kernels, XFS uses USER_HZ instead of HZ for external
# interfaces, and that is currently always set to 100. So you don't need to
# change this on 2.6.
