From 8bcbe3132c66c07d03f64d5da80be753359f2e92 Mon Sep 17 00:00:00 2001 From: Zhen Lei Date: Fri, 20 Nov 2020 17:20:57 +0800 Subject: device-dax: delete a redundancy check in dev_dax_validate_align() After we have done the alignment check for the length of each range, the alignment check for dev_dax_size(dev_dax) is no longer needed, because it get the sum of the length of each range.
