From 390600f811f1adfb9158e9b670b81219a9d94d72 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Thu, 21 May 2020 13:08:48 -0700 Subject: xfs: remove flags argument from xfs_inode_ag_walk The incore inode walk code passes a flags argument and a pointer from the xfs_inode_ag_iterator caller all the way to the iteration function. We can reduce the function complexity by passing flags through the private pointer. Signed-off-by: Darrick J.
