Re: [Virtio-fs] [for-6.1 v3 0/3] virtiofsd: Add support for FUSE_SYNCFS request

[Vivek Goyal <vgoyal@redhat.com>]

Hi Greg,

I don't see FUSE_SYNCFS support in virtiofsd. I see that kernel 
patches got merged. Did you post another version of patches?

Will be nice to add syncfs support in virtiofsd/virtiofsd_rs as well. 

Thanks
Vivek
