Cover letter [PATCH 0/2] hibernate: add config option for snapshot device
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
