NAME

       debugfs_create_dir - create a directory in the debugfs filesystem

SYNOPSIS

       struct dentry * debugfs_create_dir  (const char * name,
                                               struct dentry * parent);

ARGUMENTS

       name   a pointer to a string containing the name of  the  directory  to
              create.

       parent a  pointer  to the parent dentry for this file. This should be a
              directory dentry if set. If this paramater  is  NULL,  then  the
              directory will be created in the root of the debugfs filesystem.

DESCRIPTION

       This function creates a directory in debugfs with the given name.

       This function will return a pointer to a dentry if  it  succeeds.  This
       pointer  must be passed to the debugfs_remove function when the file is
       to be removed (no automatic cleanup happens if your module is unloaded,
       you are responsible here.) If an error occurs, NULL will be returned.

       If  debugfs  is  not  enabled  in the kernel, the value -ENODEV will be
       returned. It is not wise to check for this value, but rather, check for
       NULL  or  !NULL  instead  as  to  eliminate  the need for #ifdef in the
       calling code.
