Dear maintainers,

These are the improvements over v2 [0]:

 - switch back to atomic_t API, refcount saturates when incrementing
   from zero

These are the improvements over v1 [1]:
  
 - move the mutual exclusion to hibernate.c (it was in user.c)
 - switched to refcount_t API (it was atomic_t)
 - the option is enabled by default (it was disabled by default)
 - remove the premature "DEPRECATED" marking
 - drop the redefinition of mutual exclusion helpers (in v2 they are
   owned by hibernte.c) in case the option is deselected
 - add the help message to the config option

Kind regards,
Domenico

Both patches applied as 5.8 material with cosmetic changes in the
subjects, thanks!
