From 4af1a04176bdb4688aa14f6c10d1d5131c036a9d Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 15 Dec 2014 12:57:00 +1100 Subject: md: move GET_BITMAP_FILE ioctl out from mddev_lock. It makes more sense to report bitmap_info->file, rather than bitmap->file (the later is only available once the array is active). With that change, use mddev->lock to protect bitmap_info being set to NULL, and we can call get_bitmap_file() without taking the mutex.
