The corresponding kernel patch set:
https://lore.kernel.org/all/20211011030052.98923-1-jefflexu@linux.alibaba.com/T/#t
changes since v5:
- add back support for .ioctl()
- add back negotiation during FUSE_INIT
- add '-o dax=[server|attr]' option to control the policy used by
virtiofsd to determine whether DAX shall be enabled or not for
specific file. Please refer to the commit log of patch 4/5/6 for
more detailed information.
changes since v4:
- decide whether DAX shall be enabled or not solely depending on file
size (DAX is disabled for files smaller than 32KB)
- negotiation during FUSE_INIT is droped
- drop support for .ioctl() for passthrough
changes since v2/v3:
Patch 4 in v2 is incomplete by mistake and it will fail to be compiled.
I had ever sent a seperate patch 4 of v3. Now I send the whole complete
set in v4. Except for this, there's no other diferrence.
