* 'for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-udf-2.6:
  udf: Don't write integrity descriptor too often
  udf: Try anchor in block 256 first
  udf: Some type fixes and cleanups
  udf: use hardware sector size
  udf: fix novrs mount option
  udf: Fix oops when invalid character in filename occurs
  udf: return f_fsid for statfs(2)
  udf: Add checks to not underflow sector_t
  udf: fix default mode and dmode options handling
  udf: fix sparse warnings:
  udf: unsigned last[i] cannot be less than 0
  udf: implement mode and dmode mounting options
  udf: reduce stack usage of udf_get_filename
  udf: reduce stack usage of udf_load_pvoldesc
  Fix the udf code not to pass structs on stack where possible.
  Remove struct typedefs from fs/udf/ecma_167.h et al.
