.del-ext2_fs.h~7a460879, ChangeLog:
  ext2_fs.h (i_reserved2): Use __GNU__ instead of __hurd__ to detect the
  	Hurd OS.  To protect against future irrationality on the part of the
  	FSF concerning whether Linux is GNU or not, on a system which defines
  	both __linux__ and __GNU___, __linux__ takes precedence.
ChangeLog, initialize.c:
  initialize.c (CREATOR_OS): Use __GNU__ instead of __gnu__ to detect
  	the Hurd OS.
ChangeLog, debugfs.c:
  debugfs.c (do_dirty_filesys): Make the "dirty" command clear the valid
  	bit on the superblock.  (And with a -clean option to set the valid
  	bit.)  Originally it was used just to set the "needs to be written"
  	bit in the in-core version of the fs structure.
