The ".." interpretation is done by the client side VFS. Internal path construction does not use ".." and are always normalized. There are new situations where we now support non-absolute paths, but those are for GFID based addressing and ".." does not come into picture there.

structure. When building translators, it can also be convenient to
look at the default_xxx and default_xxx_cbk functions for each fop you
implement. Also, I forgot to mention in my comments on your "hide"
translator that you can often use the default_xxx_cbk callback when you
call STACK_WIND, instead of having to define your own trivial one.
FUSE operations are listed by the fuse_opcode enum. You can check for
yourself how closely this matches our list. They do have a few ops of
their own, we have a few of their own, and a few of theirs actually map
to our xlator_cbks instead of xlator_fops. The points of
non-correspondence seem to be interrupt, bmap, poll and ioctl. Maybe
Csaba can elaborate on what we do (or plan to do) about these.

I'll let Avati or Amar field that one.
The ".." interpretation is done by the client side VFS. Internal path construction does not use ".." and are always normalized. There are new situations where we now support non-absolute paths, but those are for GFID based addressing and ".." does not come into picture there.
