ChangeLog, closefs.c, ext2fs.h:

ChangeLog, closefs.c, ext2fs.h:
  closefs.c (ext2fs_flush): Update the s_block_group_nr field as
  	appropriate for all of the block group copies, so that it's clear
  	where the beginning of the filesystem is on the disk.  (For when the
  	partition table gets scrod.)
  ext2fs.h: Change the name of the feature from
  	EXT2_FEATURE_INCOMPAT_DIRNAME_SIZE to EXT2_FEATURE_INCOMPAT_FILESIZE
  	(to match with the kernel).
