Vivien,

One good way to start with 2.5 bugs is to compare the code to the 2.4
kernel. Often you can see places where bugs were fixed in 2.4 but the
fixes were not also made to the equivalent 2.5 code. This will keep
2.4 and 2.5 as close as possible, just like we want to keep the 64-bit
and 32-bit kernels as close as possible.
