Vivek Goyal 65a820d292 virtiofsd: Add an option to enable/disable posix acls ... fuse has an option FUSE_POSIX_ACL which needs to be opted in by fuse server to enable posix acls. As of now we are not opting in for this, so posix acls are disabled on virtiofs by default. Add virtiofsd option "-o posix_acl/no_posix_acl" to let users enable/disable posix acl support. By default it is disabled as of now due to performance concerns with cache=none. Currently even if file server has not opted in for FUSE_POSIX_ACL, user can still query acl and set acl, and system.posix_acl_access and system.posix_acl_default xattrs show up listxattr response. Miklos said this is confusing. So he said lets block and filter system.posix_acl_access and system.posix_acl_default xattrs in getxattr/setxattr/listxattr if user has explicitly disabled posix acls using -o no_posix_acl. As of now continuing to keeping the existing behavior if user did not specify any option to disable acl support due to concerns about backward compatibility.
