Subject: [PATCH v3 05/13] dax: stop requiring a live device for dax_flush()
Date: Thu, 19 Oct 2017 19:39:24 -0700 [thread overview]
Message-ID: <150846716412.24336.5216410632309453014.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <150846713528.24336.4459262264611579791.stgit@dwillia2-desk3.amr.corp.intel.com>
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.
