From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chris Mason Subject: [PATCH CFT] tons of logging patches Date: 02 Jun 2002 23:51:41 -0400 Message-ID: <1023076301.22608.1778.camel@tiny> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: list-help: list-unsubscribe: list-post: List-Id: Content-Type: text/plain; charset="us-ascii" To: reiserfs-list@namesys.com Hello everyone, ftp.suse.com/pub/people/mason/data-logging has beta code that gives you the following: external logging devices data logging mount option (makes fsync and O_SYNC faster) ordered data mount option (no more garbage in your files after a crash) optimizations to keep kupdate from triggering commits every 5 seconds optimizations for tiny transactions to reduce CPU usage and IO. optimizations for better locking and fewer calls to wakeup() In short, it adds a bunch of features and makes everything faster. The changes are very large, but they also build on older patches that have been circulating around for months. It has been through a weekend of load testing here, but I still won't be surprised if people find corruption causing bugs. It needs broad testing and benchmarking, in all the data modes, with a standard and external journal. -chris
