I had flashed Android 6.0 Marshmallow in My Nexus 5. As a part of a rooting process, I had to flash the kernel to allow SU binary to work.
All is fine and root works well.
Kernel is a intangible software component. How can I know the name and version of the kernel that I am using on my phone after installing it? I mean if I do not remember from where I downloaded the kernel or do not have the its ZIP file, are there any means with which I can find the kernel's name and its version?
