Re: [fuse-devel] fuse_file_info for chown, chgrp, utimensat, etc

[Jose L. <jab...@go...>]

I didn't know about the low-level interface until you mentioned it. In any
case, it would require a major rewrite
of our system. On the other hand, the change to pass the fuse_file_info
does not seem difficult because FUSE
already has this data structure internally, it is simply not passing it to
the user code. This change would also
make the interface more consistent, namely, it goes in the direction of the
the handler pairs getattr/fgetattr and
truncate/ftruncate.
