Hi All,

The master branch on the unionmount-testsuite tree [1] has been updated.

Changes in this update:
- Support for user configurable mount option
- Prepare to run tests with "userxattr" mount option

The previous update brought the ability for users to configure custom paths
with a custom filesystem for the underlying layers.
That ability was used to add xfstests wrappers for unionmount-testsuite.

This update brings the ability for users to configure custom overlay mount
options. This feature is also intended to be used by xfstests [2].

I used this ability to run tests with the new "userxattr" and "uuid=off"
mount option:

$ export UNIONMOUNT_MNTOPTIONS=userxattr
$ ./run --ov --verify
TEST Remove populated directory
- rmtree /mnt/a/dir106
OSError: [Errno 5] Input/output error: '/mnt/a/dir106/pop'

$ export UNIONMOUNT_BASEDIR=/vdf # (xfs filesystem)
$ ./run --ov --verify
TEST Hard link symlink
 ./run --link /vdf/m/a/direct_sym100 /vdf/m/a/no_foo100
/vdf/m/a/no_foo100: inode number/layer changed on copy up...

$ export UNIONMOUNT_MNTOPTIONS="uuid=off"
$ ./run --ov --verify

and came to the following observations:

1) rmdir test as well as other tests involving opaque dir are failing
   on tmpfs, because tmpfs does not support user.* xattrs
2) hard-link-sym test fails consistent inode number verification also
   on xfs, because symlink does not support user.* xattrs
3) All the other tests pass on xfs with the userxattr mount option
4) No failures observed with uuid=off

I did not try to run tests inside non init userns.
This practice is left to the reader.



The head of the master branch is commit:

95be14e Allow user provided options with or without -o

Amir Goldstein (3):
  Add support for user defined mount options
  Let "userxattr" mount option in UNIONMOUNT_MNTOPTIONS imply --xdev
  Allow user provided options with or without -o   |  6 ++-- |  4 +--
