From 13d59a2a61cbbb4cda13a0cba6d4d1fc537f5dd4 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 3 Jul 2019 20:36:28 -0700 Subject: xfs: specify AG in bulk req Add a new xfs_bulk_ireq flag to constrain the iteration to a single AG. If the passed-in startino value is zero then we start with the first inode in the AG that the user passes in; otherwise, we iterate only within the same AG as the passed-in inode.
