As Roman said, the warning in UPDATING only affects 2.4 <-> 2.6. So if  
you change 2.4.2 to 2.4.20, it will not result in the use of  
interfaces of a 2.6 kernel (which aren't available in -stable) by the  
linux glibc.

Now, the interesting question is: what kernel API changed between  
2.4.2 and 2.4.20, and do we support it?

The default value is not changed in -stable since ages.  And if it  
influences the results, it's a bug in the LTP tests. The tests know  
about the kernel version (at least the testsuite prints the version at  
start).

Bye,
