From 0d0676a1040d34339731a4e26a9b39b78c8a1fdf Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Thu, 6 Apr 2017 19:07:14 +0200 Subject: commit: Set commit_top_bs->total_sectors Like in the mirror filter driver, we also need to set the image size for the commit filter driver. This is less likely to be a problem in practice than for the mirror because we're not at the active layer here, but attaching new parents to a node in the middle of the chain is possible, so the size needs to be correct anyway.
