<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts: Make non-existent linker search path merely a warning
As noted in #18105, previously this resulted in a rather intrusive error
message. This is in contrast to the general expectation that search
paths are merely places to look, not places that must exist.
Fixes #18105.
(cherry picked from commit 24af9f30681444380c25465f555599da563713cb)

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">RTS: workaround a Linux kernel bug in timerfd
Reading a timerfd may return 0: https://lkml.org/lkml/2019/8/16/335.
This is currently undocumented behavior and documentation "won't happen
anytime soon" (https://lkml.org/lkml/2020/2/13/295).
With this patch, we just ignore the result instead of crashing. It may
fix #18033 but we can't be sure because we don't have enough
information.
