Wysocki The snapshot_data structure used internally by the hibernate user space interface code in user.c has three char fields that are used to store boolean values. Change their data type to bool and use true and false instead of 1 and 0, respectively, in assignments involving those fields. Signed-off-by: Rafael J.
