From 7e8275f8939988f18f9a4a596381ca215fde2270 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Mon, 4 Nov 2019 15:35:49 -0500 Subject: [PATCH] xfs_growfs: allow mounted device node as argument Up until: b97815a0 xfs_growfs: ensure target path is an active xfs mountpoint xfs_growfs actually accepted a mounted block device name as the primary argument, because it could be found in the mount table. It turns out that Ansible was making use of this undocumented behavior, and it's trivial to allow it, so put it back in place and document it this time.
