Subject: [PATCH v3 00/19][RFC] virtio-fs: Enable DAX support
Date: Wed, 21 Aug 2019 13:57:01 -0400 [thread overview]
Message-ID: <20190821175720.25901-1-vgoyal@redhat.com> (raw)
Hi,
This patch series enables DAX support for virtio-fs filesystem. Patches
are based on 5.3-rc5 kernel and need first patch series posted for
virtio-fs support with subject "virtio-fs: shared file system for virtual
machines".
https://www.redhat.com/archives/virtio-fs/2019-August/msg00281.html
Enabling DAX seems to improve performance for most of the operations
in general a great deal. I have reported performance numbers in first patch
series so I am not repeating these here.
Any comments or feedback is welcome.
Thanks
Vivek
