Repeatable barrier synchronization object

A system comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the one or more processors being configured to perform the operations of:
• detecting an event that is generated within a storage system;
• identifying a plurality of barrier objects that are associated with the event, each of the plurality of barrier objects being associated with a different respective set function, each of the plurality of barrier objects being associated with a different respective wait function, and each of the plurality of barrier objects being associated with a different respective release function;
• calling the respective set function of each of the barrier objects;
• calling the respective wait function of each of the barrier objects, wherein at least one of the respective wait functions is called before another one of the respective wait functions has returned;
• reconfiguring the storage system after all of the respective wait functions have returned;
• and
• calling the respective release function of each of the barrier objects,
• wherein at least one of the plurality of barrier objects includes:
• (i) a queue that identifies one or more threads that are executed when the storage system is reconfigured and/or (ii) a counter identifying a count of pending events that are being processed by using the given barrier object, the counter being decremented by the respective release function of the given barrier object when the respective release function of the barrier object is executed.

A non-transitory computer-readable medium storing one or more processor-executable instructions, which when executed by one or more processors cause the one or more processors to perform the operations of:

• detecting an event that is generated within a storage system;
• identifying a plurality of barrier objects that are associated with the event, each of the plurality of barrier objects being associated with a different respective set function, each of the plurality of barrier objects being associated with a different respective wait function, and each of the plurality of barrier objects being associated with a different respective release function;
• calling the respective set function of each of the barrier objects;
• calling the respective wait function of each of the barrier objects, wherein at least one of the respective wait functions is called before another one of the respective wait functions has returned;
• reconfiguring the storage system after all of the respective wait functions have returned;
• and
• calling the respective release function of each of the barrier objects,
• wherein at least one of the plurality of barrier objects includes:
• (i) a queue that identifies one or more threads that are executed when the storage system is reconfigured and/or (ii) a counter identifying a count of pending events that are being processed by using the given barrier object, the counter being decremented by the respective release function of the given barrier object when the respective release function of the barrier object is executed.
