&nbsp;<BR>&nbsp;&nbsp;Mar&nbsp;24th,&nbsp;11:57:19&nbsp;
&nbsp;<BR>
&nbsp;<BR>&nbsp;Linus&nbsp;Torvalds&nbsp;has&nbsp;released&nbsp;a&nbsp;one-liner&nbsp;fix&nbsp;to&nbsp;
&nbsp;<BR>&nbsp;the&nbsp;2.2.4&nbsp;kernel,&nbsp;which&nbsp;contains&nbsp;a&nbsp;bug&nbsp;that&nbsp;might&nbsp;
&nbsp;<BR>&nbsp;cause&nbsp;problems&nbsp;on&nbsp;heavily&nbsp;loaded&nbsp;servers.&nbsp;
&nbsp;<BR>
&nbsp;<BR>&nbsp;Linus&nbsp;writes:&nbsp;
&nbsp;<BR>
&nbsp;<BR>&nbsp;There's&nbsp;a&nbsp;potential&nbsp;problem&nbsp;under&nbsp;certain&nbsp;load&nbsp;
&nbsp;<BR>&nbsp;conditions&nbsp;with&nbsp;2.2.4,&nbsp;which&nbsp;should&nbsp;be&nbsp;fixed&nbsp;by&nbsp;
&nbsp;<BR>&nbsp;this&nbsp;one-liner.&nbsp;If&nbsp;you&nbsp;have&nbsp;trouble&nbsp;with&nbsp;2.2.4&nbsp;
&nbsp;<BR>&nbsp;(apart&nbsp;from&nbsp;the&nbsp;obvious&nbsp;one&nbsp;where&nbsp;you&nbsp;have&nbsp;to&nbsp;
&nbsp;<BR>&nbsp;add&nbsp;&quot;,&nbsp;NULL&quot;&nbsp;to&nbsp;two&nbsp;places&nbsp;in&nbsp;kernel/acct.c),&nbsp;
&nbsp;<BR>&nbsp;would&nbsp;you&nbsp;try&nbsp;this&nbsp;simple&nbsp;thing?&nbsp;
&nbsp;<BR>
&nbsp;<BR>&nbsp;Note&nbsp;that&nbsp;I&nbsp;_really_&nbsp;want&nbsp;to&nbsp;hear&nbsp;about&nbsp;if&nbsp;if&nbsp;
&nbsp;<BR>&nbsp;this&nbsp;makes&nbsp;any&nbsp;difference&nbsp;at&nbsp;all.&nbsp;It's&nbsp;a&nbsp;real&nbsp;
&nbsp;<BR>&nbsp;bug,&nbsp;but&nbsp;I&nbsp;think&nbsp;it&nbsp;needs&nbsp;some&nbsp;rather&nbsp;pathological&nbsp;
&nbsp;<BR>&nbsp;usage&nbsp;patterns&nbsp;to&nbsp;actually&nbsp;become&nbsp;a&nbsp;real&nbsp;problem.&nbsp;
&nbsp;<BR>&nbsp;So&nbsp;I'd&nbsp;like&nbsp;to&nbsp;know&nbsp;if&nbsp;it&nbsp;actually&nbsp;makes&nbsp;a&nbsp;difference&nbsp;
&nbsp;<BR>&nbsp;in&nbsp;real&nbsp;life...&nbsp;
