The _user is an annotation for Linus' sparse tool. An explanation of it is here: http://www.linuxjournal.com/article/7272 The checker source is here now: cg-clone rsync://rsync.kernel.org/pub/scm/linux/kernel/git/torvalds/sparse.git DRM fails sparse checking with 1000's of errors. Most of the failures are because DRM has unioned iomem address space pointers with ones to system memory. That is probably something that should be fixed in DRM. You can do that on the x86 but it doesn't work on all architectures. I'm sure any one who makes DRM sparse clean would get a big gold star from Linus. -- Jon Smirl [EMAIL PROTECTED] ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
