[PATCH v2 0/3] virtiofsd: Add options to enable/disable posix acl

[Vivek Goyal]

Hi,

This is V2 of the patches. Changes since v1 are.

- Rebased on top of latest master.
- Took care of Miklos's comments to block acl xattrs if user
  explicitly disabled posix acl.

Luis Henriques reported that fstest generic/099 fails with virtiofs.
Little debugging showed that we don't enable acl support. So this
patch series provides option to enable/disable posix acl support. By
default it is disabled.

I have run blogbench and pjdfstests with posix acl enabled and
things work fine.

Luis, can you please apply these patches, and run virtiofsd with
"-o posix_acl" and see if it fixes the failure you are seeing. I
ran the steps you provided manually and it fixes the issue for
me.
