befs: fix style issues in super.c

Fixing the following checkpatch.pl error:

ERROR: "foo * bar" should be "foo *bar"
+befs_load_sb(struct super_block *sb, befs_super_block * disk_sb)

And the following warnings:

WARNING: suspect code indent for conditional statements (8, 12)
+ if (disk_sb->fs_byte_order == BEFS_BYTEORDER_NATIVE_LE)
+ befs_sb->byte_order = BEFS_BYTESEX_LE;

WARNING: suspect code indent for conditional statements (8, 12)
+ else if (disk_sb->fs_byte_order == BEFS_BYTEORDER_NATIVE_BE)
+ befs_sb->byte_order = BEFS_BYTESEX_BE;

WARNING: break quoted strings at a space character
+ befs_error(sb, "blocksize(%u) cannot be larger"
+ "than system pagesize(%lu)", befs_sb->block_size,

WARNING: line over 80 characters
+ if (befs_sb->log_start != befs_sb->log_end || befs_sb->flags == BEFS_DIRTY) {

befs: fix comment style

The description of befs_load_sb was confusing the kernel-doc system since,
because it starts with /**, it thinks it will document the function with
kernel-doc formatting. Which it isn't.

Fix other comment style issues in the file while we are at it.

befs: add check for ag_shift in superblock

ag_shift and blocks_per_ag contain the same information in different ways,
same as block_shift and block_size do. It is worth checking this two are
consistent, but since blocks_per_ag isn't documented as mandatory to use
some implementations of befs don't enforce this, so making it non-fatal if
they don't match and just having it as a warning.

befs: add flags field to validate superblock state

For validating superblock state, add flags field to befs_sb_info, read the state from the disk
and check if it is equal to BEFS_DIRTY.

befs: fix function name in documentation

Documentation of function befs_load_cb() lists it as load_befs_sb(). Fix
the misnomer.

Linux-2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
