<aia21@cantab.net> (02/06/26 1.603.1.2) NTFS: 2.0.12 - Initial cleanup of address space operations following 2.0.11 changes. - Merge fs/ntfs/aops.c::end_buffer_read_mst_async() and fs/ntfs/aops.c::end_buffer_read_file_async() into one function fs/ntfs/aops.c::end_buffer_read_attr_async() using NInoMstProtected() to determine whether to apply mst fixups or not. - Above change allows merging fs/ntfs/aops.c::ntfs_file_read_block() and fs/ntfs/aops.c::ntfs_mst_readpage() into one function fs/ntfs/aops.c::ntfs_attr_read_block(). Also, create a tiny wrapper fs/ntfs/aops.c::ntfs_mst_readpage() to transform the parameters from the VFS readpage function prototype to the ntfs_attr_read_block() function prototype.
