Subject: lib/pager: Remove unused code
X-Git-Tag: v2.43-devel~48^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cb3942d0a80797becb80e177602de4fba9c864d4;p=thirdparty%2Futil-linux.git

lib/pager: Remove unused code

The pager_process.pid check already happens before wait_for_pager is
called now.

Also, errno is not used anymore after the signal handler, so no need to
save it.
