From b26313cb96f1b3fd6f07d3243f6cd426c5cbaf39 Mon Sep 17 00:00:00 2001 From: Yu Kuai Date: Mon, 26 Aug 2024 15:44:31 +0800 Subject: md/md-bitmap: merge bitmap_write_all() into bitmap_operations So that the implementation won't be exposed, and it'll be possible to invent a new bitmap by replacing bitmap_operations. Also change the parameter from bitmap to mddev, to avoid access bitmap outside md-bitmap.c as much as possible.
