I get the relaxing part when it comes to RCU read lock but why does it
carry fixes tag? The commit message does not do a great job on
explaining this part.

It's the first part of a multipatch fix (it was originally in one patch and I
just duplicated the Fixes).  I can remove the Fixes line though - as you point
out, this patch is not technically a fix in itself.
