so ll_rw_block can setup the bio op and bi_rw flags on the bio that

Use the current logging styles.

Convert a few printks that should have been udf_warn and udf_err.
Coalesce formats.  Add #define pr_fmt.
Move an #include "udfdecls.h" above other includes in udftime.c
so pr_fmt works correctly.  Strip prefixes from conversions as appropriate.
Reorder logging definitions in udfdecl.h

Position in directory returned by readdir is offset of directory entry divided
by four (don't ask me why).  Make this conversion only when reading f_pos from
userspace / writing it there and internally work in bytes.  It makes things
more easily readable and also fixes a bug (we forgot to divide length of the
entry by 4 when advancing f_pos in udf_add_entry()).

inode_getblk always set 4th argument to uint32_t value
3rd parameter of map_bh is sector_t (which is unsigned long or u64)
so convert phys value to sector_t

udf_get_filelongad and udf_get_shortad are called always for uint32_t
values (struct extent_position->offset), so it's safe to convert offset
parameter to uint32_t

Use sector_t and loff_t for file offsets in UDF filesystem.  Otherwise an
overflow may occur for long files.  Also make inode_bmap() return offset in
the extent in number of blocks instead of number of bytes - for most

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!
