From: Sreenivasa Honnur Date: Thu, 10 May 2007 08:22:25 +0000 (-0400) Subject: S2IO: Statistics for link up/down and memory allocated/freed X-Git-Tag: v2.6.22-rc1~20^2~14 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=491976b2bce07f2c44e32a987fa6eb9edf8b0aeb;p=linux-2.6 S2IO: Statistics for link up/down and memory allocated/freed 1. Added statistics for link up/down, last link up/down. 2. Statistics for memory allocated/freed. 3. Changed level of some DBG_PRINTs.
