Subject: [PATCH 2/4] fs/ntfs3: Rename bitmap_size() as ntfs3_bitmap_size()
Date:   Sat,  2 Jul 2022 20:29:27 +0200
Message-Id: <56a3cb896ec446ca24e4756042d9f0829afc671a.1656785856.git.christophe.jaillet@wanadoo.fr>

In order to introduce a bitmap_size() function in the bitmap API, we have
to rename functions with a similar name.

Add a "ntfs3_" prefix and change bitmap_size() into ntfs3_bitmap_size().

No functional change.
