Methods, electronic devices and computer program products for storage management

An electronic device, comprising:

• at least one processor;
• and
• at least one memory storing computer program instructions, the at least one memory and the computer program instructions being configured to cause, with the at least one processor, the electronic device to perform actions comprising:
• determining, if it is determined that lock information associated with a lock operation performed on an object is to be inserted into a storage device, a target digest for representing the lock information;
• determining whether an idle index not associated with a historical digest exists in an index array for indicating a plurality of storage positions in the storage device;
• and
• inserting, if it is determined that an idle index exists in the index array, the lock information into a target storage position in the plurality of storage positions by associating the target digest with the idle index.

A computer program product having a non-transitory computer readable medium which stores a set of instructions to perform storage management;

• the set of instructions, when carried out by computerized circuitry, causing the computerized circuitry to perform a method of:
• determining, if it is determined that lock information associated with a lock operation performed on an object is to be inserted into a storage device, a target digest for representing the lock information;
• determining whether an idle index not associated with a historical digest exists in an index array for indicating a plurality of storage positions in the storage device;
• and
• inserting, if it is determined that an idle index exists in the index array, the lock information into a target storage position in the plurality of storage positions by associating the target digest with the idle index.
