From e5d74902362f1a06ea3674042d09f1af178c0a20 Mon Sep 17 00:00:00 2001 From: David Sterba Date: Tue, 14 Feb 2017 19:45:05 +0100 Subject: btrfs: derive maximum output size in the compression implementation The value of max_out can be calculated from the parameters passed to the compressors, which is number of pages and the page size, and we don't have to needlessly pass it around.
