This is last line code of the function, so it's always return the

There are some checking like ubifs_initialized in the cmd/ubifs.c.
Direct callng the function would bypass those checking.

kerneldoc doesn't has explanation for this function, and this function
is not for user. Or you means i shouldn't put the comment and
