From 062647a8b41928f4fb97f967b24092be68f5f0f0 Mon Sep 17 00:00:00 2001 From: Brian Foster Date: Fri, 28 Nov 2014 14:00:16 +1100 Subject: xfs: replace on-stack xfs_trans_res with pointer in xfs_create() There's no need to store a full struct xfs_trans_res on the stack in xfs_create() and copy the fields. Use a pointer to the appropriate structures embedded in the xfs_mount.
