I've been debugging an issue in my linux kernel and have found a fix for the issue. Checking cross reference, I can see that the fix was applied to that file between kernel version A and kernel version B.

What is the best way to find the patch the exact patch that this fix got checked in with? I would like to see if there are other issues that are fixed with the same patch.

Thing I know:

  • Exact file and line of code that changed
  • Kernel version where the bug was present and the version that it was fixed in

Thanks!

You might get somewhere browsing the torvalds git tree, eg for the file time/hrtimer.c. Click on blame and for each line number you see the last patch applied. You can also browse the history for older patches.
