THREAD MANAGEMENT IN A STORAGE SYSTEM

Described embodiments provide systems and methods for operating a storage system. The storage system may generate one or more input/output (I/O) caller threads. For each of the I/O caller threads, one or more background provider threads may be generated that may be associated with the I/O caller thread. Instructions associated with the I/O caller threads and the background provider threads may be performed. Each of the one or more background provider threads may be synchronized with the associated I/O caller thread. Each thread may check a state of the associated threads, and based upon the state of the associated threads, each thread may post a state indicator to a mailbox field in a context of the associated threads.
