I need to convert an integer to it's ASCII representation from within the Linux Kernel. How can I do this? I can't find any built-in conversion methods. Are there any already in the kernel or do I need to add my own?

That is why I want to edit/patch the source of only that single kernel module to add some extra debug output. The kernel module in question is mvsas and not necessary to boot. For that reason I don't… >>> More

I have also read http://www.linuxjournal.com/article/8110 However, problem is 2.6.30 does not export sys_read(). Rather its wrapped in SYSCALL_DEFINE3… >>> More
