49126e47bf staging/lustre: lloop depends on BLOCK
Add a config option for llite/lloop in lustre driver, making it depends
on BLOCK to fix this better:
drivers/staging/lustre/lustre/fid/../include/linux/lustre_compat25.h:117:2:
error: implicit declaration of function ‘unregister_blkdev'

Also, remove the wrapper ll_unregister_blkdev which depends on BLOCK in
the header and just call unregister_blkdev in lloop.c based on Peng Tao's
comment. Drop the redundant dependency on STAGING for LUSTRE_FS, remove
some unnecessary jdb header files which depends on BLOCK btw.

631abc6e65 staging/lustre/obdclass: use a dummy structure for lu_ref_link
Move the definition of struct lu_ref_link to lu_ref.h.  If USE_LU_REF
is not defined then define it to be the empty struct.  Change the
return type of lu_ref_add() and lu_ref_add_atomic() to void.  Add
lu_ref_add_at() taking same arguments as lu_ref_add() togerther with a
pointer to a struct lu_ref_link and returning void.  Adjust all
structures containing a lu_ref_link pointer to contain a struct
lu_ref_link instead.  Use lu_ref_add_at() and lu_ref_del_at() to
handle embedded lu_ref_links.

[Original patch mainly changes lu_ref.[ch] but in upstream client we don't
have lu_ref code in the hope of moving to kobject refcounting. So the patch
only picks the other pieces of original patch, in order to keep code in
sync and make it easier to port future patches.]
