From 129f809d2aa9c02cd1ab9714b265d828db3691ec Mon Sep 17 00:00:00 2001 From: David Howells Date: Mon, 25 Mar 2019 16:38:29 +0000 Subject: [PATCH] vfs: Convert ibmasmfs to use the new mount API Convert the ibmasmfs filesystem to the new internal mount API as the old one will be obsoleted and removed. This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information.
