[PATCH v2 0/2] viritofsd: Add support for FUSE_HANDLE_KILLPRIV_V2

Posted by Vivek Goyal 3 years, 6 months ago

Hi,

This is V2 of patches to add support for FUSE_HANDLE_KILLPRIV_V2. This
is basically a feature file server can opt-in. And with xattr enabled,
this improves write performance many fold (jumps from 50MB/s to
300MB/s approx).

kernel patches have now been staged in for-next branch of fuse tree by Miklos.

https://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git/log/?h=for-next

I tested virtiofsd with these patches and things look good to me.
Posting now for review and inclusion as soon as kernel patches are
merged in 5.11.

Thanks
Vivek
