I think you can get it by call path_lookup(const char *path, unsigned
flags, struct nameidata *nd)

"path_lookup" may not be exported by some kernel versions, instead you can use "path_init" and "path_walk" together to get the inode info.  Further you will get the inode info from the dentry field in nameidata structure. See the code of path_lookup if you have any doubts.
