[Libguestfs] [PATCH] Reserve entries to tsk_dirent struct

Already implemented entries.

tsk_inode
tsk_type
tsk_size
tsk_name
tsk_flags

Easy ones to add.

tsk_atime_sec
tsk_atime_nsec
tsk_mtime_sec
tsk_mtime_nsec
tsk_ctime_sec
tsk_ctime_nsec
tsk_blksize
tsk_blocks

Further ideas.

tsk_nlink
tsk_link_name

First a note: This patch is only valid because we have not yet
released this API in a stable release of libguestfs.  After an API
becomes stable we never change it.

I'm a bit confused - what is the aim of this patch?  Is it to reserve
fields we might implement in future, and if so, why don't we just
implement them now?

This is why I am reserving them now.>

The patch to add new fields is still a WIP.
If the next stable release due date is still far then you can NACK this 
patch.>
