[PATCH v6 0/8] virtiofsd: Add support to enable/disable posix acls

[Vivek Goyal <vgoyal@redhat.com>]

Hi,

This is V6 of the patches.

Changes since V5:

- Kernel patches for extended setxattr have been merged in 5.13-rc1.
  These patches have been modified to work with FUSE_SETXATTR_EXT.

Currently posix ACL support does not work well with virtiofs and bunch
of tests fail when I run xfstests "./check -g acl".

This patches series fixes the issues with virtiofs posix acl support
and provides options to enable/disable posix acl (-o posix_acl/no_posix_acl).
By default posix_acls are disabled.

With this patch series applied and virtiofsd running with "-o posix_acl",
xfstests "./check -g acl" passes.

Thanks
Vivek
