From 5ca7467fe86071dfaed6b4dd99daea992229fb31 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Wed, 10 Nov 2021 09:38:10 -0800 Subject: xfs: #ifdef out perag code for userspace The xfs_perag structure and initialization is unused in userspace, so #ifdef it out with __KERNEL__ to facilitate the xfsprogs sync and build.
