Hi,
For my driver I needed to allocate a contigous 1Mb buffer. kmalloc() is
unable to allocate more than 128kb, so I went and fixed slab.c to allow
allocation of 256k, 512k and 1M slabs. I can allow that, since a device I
work on will be shipped in a closed preinstalled box.
The question is, since it is so trivial, there must be a really good
reason to disallow slabs of more that 128kb. Otherwise, it would have been
done years ago. It seems to me practical to kmalloc even larger blocks of
memory. What is that reason?
