From 55bcd62d06fa33d8c99bdc58c57f6dd313b6220b Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Wed, 14 Aug 2019 18:05:17 -0400 Subject: [PATCH] xfs: specify AG in bulk req Source kernel commit: 13d59a2a61cbbb4cda13a0cba6d4d1fc537f5dd4 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.
