Seems I've picked up a wireless regression, and randomly drop my WiFi
connection with more recent kernels. While I'd love to try to track down the
issue, the sporadic nature makes it difficult. But I don't want to revert to a
flat-out old kernel because of all the btrfs modifications. Is it possible
using git to add *just* btrfs patches to an older kernel?
Thanks,
-Ken

Sure: use git rebase to apply the patches to the older kernel.

=2E.. or use 3.1.2, and get ONLY fs/btrfs from Chris' for-linus tree,
compile it out-of-tree, and use it to replace the original btrfs.ko.
There used to be this:
https://btrfs.wiki.kernel.org/articles/b/t/r/Btrfs_source_repositories.=
html#Building_latest_btrfs_against_a_recent_kernel_with_DKMS
But personally it's much easier to just compile it manually without dkm=
s:
make -C /llib/modules/`uname -r`/build M=3D$(pwd) modules

If you're on a 3.1 kernel, you can pull my for-linus directly on top of
it with git pull. I always keep a btrfs tree against the previous
kernel so that people can use the latest btrfs goodness without having
to use an rc kernel.

Yes, thanks for that.
My suggestion is simply an alternative (instead of git pull) for people=
who:
- aren't quite familiar with git, but know enough to grab a directory
snapshot from gitweb (e.g.
http://git.kernel.org/?p=3Dlinux/kernel/git/mason/linux-btrfs.git;a=3Dt=
ree;f=3Dfs/btrfs;h=3D5f51bd7e3b8b6c4825681408450e6580bdbccce1;hb=3Drefs=
/heads/for-linus)
- know how to build a module out-of-tree
- on the latest stable, but don't want to re-compile the whole kernel
just to get btrfs fix
