Do you mean a better/longer commit message?

I felt that the Subject: and Fixes: says it all and didn't
want to duplicate information (contained in its commit
message and comments added by that change, as well as the
very paragraph we're updating here).

Would adding something like

  The pipe size limit used when the fs.pipe-user-pages-soft
  sysctl value is reached was increased from one to two
  pages in commit 46c4c9d1beb7; update the documentation to
  match the new reality.

work?

Thank you,
