Abstract

For reducing lock contention on a Modified Least Recently Used (MLRU) list for metadata tracks, upon a conclusion of an access of a metadata track, if one of the metadata track is located in a predefined lower percentile of the MLRU list, and the metadata track has been accessed, including the access, a predetermined number of times, the metadata track is removed from a current position in the MLRU list and moved to a Most Recently Used (MRU) end of the MLRU list.
