From 6a21586a637e624ae736f94aeb0839f6a1dd0411 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Sat, 14 Oct 2017 17:42:02 -0700 Subject: dax: stop requiring a live device for dax_flush() Now that dax_flush() is no longer a driver callback (commit c3ca015fab6d "dax: remove the pmem_dax_ops->flush abstraction"), stop requiring the dax_read_lock() to be held and the device to be alive. This is in preparation for switching filesystem-dax to store pfns instead of sectors in the radix.
