Re: [PATCH 0/21] KGDB: Request to merge KGDB
Hi! This is a request to merge KGDB into the mainline kernel. This won't work very well. There's a lot of review work to be done here, and a lot of it by busy architecture maintainers. Expecting people to do all this review and test work late in the merge window when they're all madly scrambling to get their bugs^Wpatches into mainline is not reasonable. This should all have started a month ago. _If_ the code is properly bisectable, it should be possible to merge core now and then switch architectures lazily. (If it is not bisectable, it should be fixed).

I don't think a utrace merge as in one big merge is going to happen ever. It's just a too big patch doing too many things at once.

What would be good is if some effort could be made by the utrace- interested parties to make the transition to utrace much less painful. For instance, I quite like the getregs/setregs abstractions, and it looks like these *could* be self-contained in a single patch.
