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?

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 dkms: make -C /llib/modules/`uname -r`/build M=$(pwd) modules -- Fajar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

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. -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

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=linux/kernel/git/mason/linux-btrfs.git;a=tree;f=fs/btrfs;h=5f51bd7e3b8b6c4825681408450e6580bdbccce1;hb=refs/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 -- Fajar -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
