From: Roberto Nibali Date: Tue, 3 Jan 2006 22:22:59 +0000 (-0800) Subject: [IPVS]: Cleanup IP_VS_DBG statements. X-Git-Tag: v2.6.16-rc1~474^2~22^2~9^2~18 X-Git-Url: http://pileus.org/git/?a=commitdiff_plain;h=4b5bdf5cc3695dc5caba011b9c616b40e6299638;p=~andy%2Flinux [IPVS]: Cleanup IP_VS_DBG statements. From: Roberto Nibali The attached patch (against current -GIT) is a cleanup patch which does following: o lookup debug messages shifted back to 9 o added more informational value to flags and refcnt since those entries can be in multiple referenced structures o cleanup 80 char violation It's the prepatch to the session pool implementation and helps very much to debug and monitor important variables and structures regarding the threshold limitation and persistency without the thousands of lookup messages which noone is interested in.
