"Since" more clearly says what happens in Linux 5.13 and Linux 5.15. Also, this sentence doesn't seem to relate to the one-page limit mentioned in this paragraph, which is only when the soft limit for the number of pipes has been reached. It seems to say that this limit is the default limit of individual pipes, with no mention to the soft limit of pipes. And also, I would mention the current behavior first, and only as a note the historic behavior, instead of first mentioning the historic behavior and later the current one. Instead of your proposal, I would do: -individual pipes created by a user will be limited to one page, +individual pipes created by a user will be +limited to two pages +(one page before Linux 5.14), and attempts to increase a pipe's capacity will be denied.
