Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[PATCH] move cnodeid_to_nasid_table out of pda Another step in the effort to eliminate the SN pda structure. This patch moves the cnodeid_to_nasid_table field out of the pda, making it a standalone per-cpu data item, and exports it so it can be accessed by kernel modules.
