From 1415f402e1a1e6054377ed15f249589204cfb8b7 Mon Sep 17 00:00:00 2001 From: Yu Kuai Date: Mon, 26 Aug 2024 15:44:37 +0800 Subject: md/md-bitmap: merge md_bitmap_end_sync() 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.
