How to contribution linux kernel

I’m interested in Linux Kenrel and wanted to contribute.
So i will keep it in documentation and try to contribution whenever find a bug or extra.

1. Pull Linux mainline kernel source code

   git clone https://github.com/torvalds/linux.git ./mainline_code
   

2. Configure git environment

   git config --global user.name "JJungs Lee"
   git config --global user.email "loveljhs2@gmail.com"
   git config --global core.editor vi
   // --snip--
   

3. Modify the code (Bugs or New features)

   // test.c
   -int num = 0;
   +long long num = 0;
   

4. Git add modify files and commit use -s or --signoff option
   (add Signed-off-by in commit)

   git add test.c
   git commit -s -m "test for commit"
   

5. Make patch file and Check linux coding style
   If the coding style is mismatch, the checkpatch tool will be prints errors. All errors, warnings, spaces, etc. need to be fixed.

   git format-patch -1
   ./scripts/checkpatch.pl ./0001-test-for-commit.patch
   

6. Check maintainers, submitter and mailing list

   ./scripts/get_maintainer.pl ./0001-test-for-commit.patch
   

7. Install the git-email for sending patchs

   sudo apt-get install git-email
   

8. Send patch files to maintainers using git send-email
