From f736d93d76d3e97d6986c6d26c8eaa32536ccc5c Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Thu, 21 Jan 2021 14:19:58 +0100 Subject: xfs: support idmapped mounts Enable idmapped mounts for xfs. This basically just means passing down the user_namespace argument from the VFS methods down to where it is passed to the relevant helpers. Note that full-filesystem bulkstat is not supported from inside idmapped mounts as it is an administrative operation that acts on the whole file system. The limitation is not applied to the bulkstat single operation that just operates on a single inode.
