From cdc9cec7c0ff521edf8c0e9c9432bf8fdccfc702 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Thu, 4 Dec 2014 09:42:40 +1100 Subject: xfs: active inodes stat is broken vn_active only ever gets decremented, so it has a very large negative number. Make it track the inode count we currently have allocated properly so we can easily track the size of the inode cache via tools like PCP.
