From 32f61d67570db036dba9e4fb2509b5343e28f627 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 1 Sep 2020 17:57:47 +0200 Subject: nvdimm: simplify revalidate_disk handling The nvdimm block driver abuse revalidate_disk in a strange way, and totally unrelated to what other drivers do. Simplify this by just calling nvdimm_revalidate_disk (which seems rather misnamed) from the probe routines, as the additional bdev size revalidation is pointless at this point, and remove the revalidate_disk methods given that it can only be triggered from add_disk, which is right before the manual calls.
