Hi,
I don't know how __iomem and __user work, and can you help?
No, but I might know a man who can.
Another problem what does sparse mean?
A little time on Google shows that in the context of "__iomem" and
"__user", you probably mean the "SPARSE" tool which is a static
analysis tool for C, as far as I can tell from a very brief look at
http://www.kernel.org/pub/software/devel/sparse/ - "__iomem" and
"__user" appear to be code annotations which SPARSE understands, but I
could well be mistaken.
This is nothing to do with the C language as such, and all to do with
using C to write the Linux kernel. You should start by looking at the
SPARSE webpages, and any further questions probably belong in the
comp.os.linux.development newsgroup hierarchy - probably
comp.os.linux.development.system, I think - rather than comp.lang.c.
There is also a SPARSE mailing list - details on the webpage.
