From 1998764e5a1700ffad2cab29b7b2a175364e5b70 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Tue, 27 Jun 2006 16:12:40 +1000 Subject: [PATCH] [XFS] Reduce size of xfs_trans_t structure. * remove ->t_forw, ->t_back -- unused * ->t_ag_freeblks_delta, ->t_ag_flist_delta, ->t_ag_btree_delta are debugging aid -- wrap them in everyone's favourite way. As a result, cut "xfs_trans" slab object size from 592 to 572 bytes here.
