From 1ac994525b9d3b6245c1a61632156f19ab73fccb Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Thu, 5 Mar 2020 07:21:43 -0800 Subject: iomap: Remove pgoff from tracepoints The 'pgoff' displayed by the tracepoints wasn't a pgoff at all; it was a byte offset from the start of the file. We already emit that in the form of the 'offset', so we can just remove pgoff. That means we can remove 'page' as an argument to the tracepoint, and rename this type of tracepoint from being a page class to being a range class.
