            Bug ID: 1196607
           Summary: Any op on files in the root directory of the volume
                    fails unless absolute path is specified.
           Product: Red Hat Storage

+++ This bug was initially created as a clone of Bug #1196019 +++

Description of problem:
If a test case is as follows: 
....
fs = glfs_init();
....
glfs_mkdir(fs, "dir1", 0755); /* dir1 being relative to the root of the
volume*/
...
glfs_fini();

The above test case fails for the below reason:

glfs_init() does not set the cwd to be "/", Hence with this patch the
expectation would be that the path should be absolute always for a file
directory under "/". i.e. the below statement succeeds:
    glfs_mkdir (fs, "/dir1", 0755);
Expecting absolute patch for any file directly under "/", may break the
existing users.

Two possible fixes:

In glfs_init(), set fs->cwd to "/", not sure if there can be other cases where
it can be unset.
In glfs_resolve_path() even if glfs_cwd_get() returns NULL, call
priv_glfs_resolve_at() as it handles that case.
