Summary: open("/etc/ld.so.conf", O_RDONLY|O_EXCL) = -1 EEXIST

Initial Comment:
calling open(2) with RDONLY|EXCL is handled incorectly?
 It returns the error file exists.  the only time it
should return that error is when O_CREAT and O_EXCL is
used together.  I've been busy learning the innards of
the openssi kernel code these past few weeks, and i
think (but not sure) it has something to do with the
context symlink code in fs/namei.c and fs/open.c

openssi-debian (RC4)
`ldconfig -v` to produce the error.

i found this bug adding my /usr/X11R6/lib directory to
/etc/ld.so.config file

How about int cfs_open() in cluster/ssi/cfs/inode.c
                                                           
                                                           
                                                           
                                
+       if ((filp->f_flags & O_EXCL)
+           && !(CFS_FLAGS(inode) & CCREATED)) {
+               error = -EEXIST;
+               goto out;
                                                           
                                                           
                                                           
                                
Perhaps that needs to be changed into something like:
+       if (((filp->f_flags & O_EXCL) && (filp->f_flags &
O_CREAT))
