I will resend request with field updated. ok, things which usually help are: 'git log -SLPM -- drivers/usb/gadget/composite.c' this will help you find commits which have the string LPM in their body and touch drivers/usb/gadget/composite.c 'git describe' this will tell you when a commit was merged. Keep in mind that a commit reaches a maintainer tree before Linus tags something, so if git describe says: v3.0-rc3-212-gfoobar, that means commit reaches mainline during v3.1 merge window. Documentation/stable_kernel_rules.txt This tells what a stable patch should look like 'git remote add stable \ git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git \ && git fetch stable && git log stable/linux-3.14.y' This would help you see actual commits in a stable tree so you can mimic the format. cheers -- balbi
