[PATCH v3 18/21] read-cache: refactor read_index_from()

From: Christian Couder <hidden>
Date: 2016-12-26 10:23:21
Subsystem: the rest · Maintainer: Linus Torvalds

It looks better and is simpler to review when we don't compute
the same things many times in the function.

It will also help make the following commit simpler.
