[Libsysio-commit] unification: libsysio configure.in

[Lee W. <lw...@us...>]

Update of /cvsroot/libsysio/libsysio
In directory sc8-pr-cvs6.sourceforge.net:/tmp/cvs-serv6564

Modified Files:
      Tag: unification
	configure.in 
Log Message:


The open file table now maintains a link to the path-node, or `pnode', instead
of the inode. This is done in order to enable support for per-mount options.

The issue is that bound-mounts could not have independent options. We had lost
the linkage between the mount that a particular alias came from and, so,
could not act on per-mount flags.

As part of this, all calls through the VFS have been wrapped by macros. They
all begin with PNOP_. For instance, the inop_mkdir call is wrapped with
PNOP_MKDIR now.

These modifications, while intrusive, require no changes to the existing
drivers. However, there are many calls that take both a path-node and an
inode, and at some time in the future, the path-node, only, will be passed.
You might be pro-active in altering the various entry-points so that the
inode is ignored -- It's always available now. Of course, that can't be
done for the IO routines, which take only an inode. Note, though, that the
ioctx structure now carries the path-node, in addition. Perhaps use that? In
short, I'm going to deprecate the passing of inodes through the VFS in favor
of the path-node at some point.
