From 49fa7a590208b439cc74f2cafdb15568abb3f8d1 Mon Sep 17 00:00:00 2001 From: Ryusuke Konishi Date: Sat, 14 Nov 2009 16:44:22 +0900 Subject: [PATCH] nilfs2: add palloc cache to ifile This adds the palloc cache to ifile. The palloc cache is allocated on the extended region of nilfs_mdt_info struct. The struct nilfs_ifile_info defines the extended on memory structure of ifile.
