It's better to read as a single line here

[2]: commit b86ff981a825 ("[PATCH] relay: migrate from relayfs to > a generic relay API")

OR you can even have it as a proper Link tag:

Link: https://git.kernel.org/torvalds/c/b86ff981a825 [2]

Same for the rest.

Note, when converting to Link tags the above, this blank line should be
removed.
