Command line tips and tricks - ClangBuiltLinux/linux GitHub Wiki
Given sha of commit, we want to know the first tag that contains the fix.
tag=$1
git describe --match 'v*' --contains "$tag" | sed 's/[~^].*//'$ git log -S <string> <file>(via Saravana Kannan)
$ git show --format=format:'commit %h ("%s")' 69d0db01e210e07fe915e5da91b54a867cda040f | head -n1
commit 69d0db01e210 ("ubsan: remove CONFIG_UBSAN_OBJECT_SIZE")Can also be done with git's formatter.
Add this to your .gitconfig file:
[pretty]
commit = commit %h (\"%s\")
And then generate the formatted message like so:
$ git log -1 --pretty=commit 2de9e73d252d2f1100fcf4dfd7013cc4a93d82d6
commit 2de9e73d252d ("nfsd: use correct format characters")Similarly can be done for Fixes: ... messages.

Recommend installing b4.
Examples:
# Link to patch (series)
link="https://lore.kernel.org/r/[email protected]/"
or
link="https://lore.kernel.org/lkml/[email protected]/"
# Apply patch (series) in local Git
$ b4 am $link -o - | git am
# Download patch (series)
$ b4 -d am $link$ sudo rm -r /boot/config-$(uname -r) /boot/initrd.img-$(uname -r) /boot/System.map-$(uname -r) /boot/vmlinuz-$(uname -r) /lib/modules/$(uname -r)Simulate the check of your patch:
$ cd /path/to/linux.git
$ git send-email --dry-run --to-cmd='scripts/checkpatch.pl' 0001-Makefile-correct-prefix-for-Clang-builds.patch
Simulate to get the list of maintainers:
$ git send-email --dry-run --to-cmd='scripts/get_maintainer.pl -i' 0001-Makefile-correct-prefix-for-Clang-builds.patch
- Note: Drop
--dry-runfor a real submission. - Note: Install the package of your distribution shipping
