For 1k-block filesystems, the filesystem starts at block 1, not block 0. This fact is recorded in s_first_data_block, so use that to bump up the start_fsb before we start querying the filesystem for its space map. Without this, ext4/026 fails on 1k block ext4 because various functions (notably ext4_get_group_no_and_offset) don't know what to do with an fsblock that is "before" the start of the filesystem and return garbage results (blockgroup 2^32-1, etc.) that confuse fsmap.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
