On file systems that support it, this can dramatically speed up operations like add, commit, describe, rebase, reset, rm that would otherwise have to lstat() every file to "re-match" the stat information in the index to that of the file system. On a synthetic repo with 1M files, "git reset" dropped from 52.02 seconds to 14.42 seconds for a savings of 72%. Signed-off-by: Ben Peart <Ben.Peart@microsoft.com>
