Comment (by iandunn):

 > should the version be 2.8?

 I think it's supposed to represent
 [https://make.wordpress.org/core/handbook/contribute/trac/#ticket-
 properties the version where the bug was introduced].

 > This doesn't seem directly related to r49744; it looks like it goes all
 the way back to when the concept of expiration was added to transients in
 r10603. ... dirsize_cache was added for Multisite instances when Multisite
 was merged to Core in r12603.
