Subject: [PATCH 0/4] fstests: fixes for config option OVERLAY_MOUNT_OPTIONS
Date: Wed, 27 Sep 2017 10:04:08 +0300 [thread overview]
Message-ID: <1506495852-7295-1-git-send-email-amir73il@gmail.com> (raw)
Eryu,
Since v4.13, overlayfs supports mount option index=on/off per mount
and kernel config option CONFIG_OVERLAY_FS_INDEX that sets the default
system wide value when mount option is not specified.
The behavior of overlayfs may differ for index=on/off, specifically
for hardlinks. It is therefore important to be able to test overlayfs
with both index=on/off.
To that end exists the OVERLAY_MOUNT_OPTIONS config option, only
when I tried to use it I found it was broken in more than one way.
This series fixed the use of OVERLAY_MOUNT_OPTIONS and refactors
some customized overlay mount helpers along the way.
NOTE for users of kvm-xfstests, this test-appliance change is also
required for invoking kvm-xfstests -m index=on/off
