Sure. The stock 2.6.9 kernel doesn't include kzalloc() or kstrdup().
However, both of those exist in the Red Hat RHEL4 U3 and later kernels
(yeah, I know, there isn't an easy way to know this, but unless you just
*need* to support a U2 or earlier kernel, then you can just assume Red
Hat has this). Likewise, the U4 and later kernels have the proper class
functions in the core kernel so you don't need small backports of stuff
like class_create in the uverbs_main patch. Ditto for the get_sb_psuedo
in the core patch. Ditto for a number of things in the ipath backports.
Ditto for quite a few other things as well. In general, there's less
need to backport under RHEL4 U4 than previously, and where possible it
would be best to make use of the core kernel's enhancements relative to
a stock 2.6.9.
