From cf7b7e1492e97dd0c44479239742eb4cb752eeed Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Fri, 1 Mar 2013 18:00:15 -0600 Subject: ceph: use calc_pages_for() in start_read() There's a spot that computes the number of pages to allocate for a page-aligned length by just shifting it. Use calc_pages_for() instead, to be consistent with usage everywhere else. The result is the same. The reason for this is to make it clearer in an upcoming patch that this calculation is duplicated.
