Patch

View in context: <a href="https://bugs.webkit.org/attachment.cgi?id=273748&amp;action=review">https://bugs.webkit.org/attachment.cgi?id=273748&amp;action=review</a>

Looks good to me, but I think it makes sense to have someone more closely involved with the port sign off an polling proc every second.

<span class="quote">&gt; Source/WebCore/platform/linux/MemoryPressureHandlerLinux.cpp:56
&gt; +static const size_t s_memoryCriticalLimit = 100 * KB * KB; // 100 MB
&gt; +static const size_t s_memoryNonCriticalLimit = 300 * KB * KB; // 300 MB</span >

It might be worth discussing a bit where these numbers come from. A comment here or a note in the ChangeLog or bug is fine.

<span class="quote">&gt; Source/WebCore/platform/linux/MemoryPressureHandlerLinux.cpp:224
&gt; +    if (!installUsingCgroups() &amp;&amp; !installUsingMeminfo())
&gt; +        return;</span >

Much nicer!

<span class="quote">&gt; Source/WebCore/platform/linux/MemoryPressureHandlerLinux.cpp:227
&gt;      if (ReliefLogger::loggingEnabled() &amp;&amp; isUnderMemoryPressure())
&gt;          LOG(MemoryPressure, &quot;System is no longer under memory pressure.&quot;);</span >

This is quite strange. If isUnderMemoryPressure returns true, a message is printed that the system is not under memory pressure. Do you have understand why this is?</pre>
