My practice says it isn't, but glibc is (sizeof(fd_set)). If your
glibc uses kernel headers of the running kernel, then fixing up
the kernel headers might have a direct result on glibc. But not
really on the actual kernel !!

Then they are misinformed.

They are talking about linux 2.2.5. The 1024 fd limitation was lifted
in more recent 2.2.x kernels (2.2.12 and up, like Henrik said).
