From 7492c5b42de857c13d8b7e0dafb2a5e331598e00 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Mon, 12 Aug 2013 20:50:05 +1000 Subject: xfs: Reduce allocations during CIL insertion Now that we have the size of the object before the formatting pass is called, we can allocation the log vector and it's buffer in a single allocation rather than two separate allocations. Store the size of the allocated buffer in the log vector so that we potentially avoid allocation for future modifications of the object. While touching this code, remove the IOP_FORMAT definition.
