    sys/gnu/ext2fs       ext2_linux_ialloc.c fs.h 
  Log:
  Quick fix for not being able to sync all the buffers in boot() if
  an ext2fs file system is mounted.  The soft update changes added
  a check for B_DELWRI buffers.  This exposed the complete brokenness
  of the previous quick fix for failing syncs (PR 3571, committed on
  1997/08/04).  Use a new buffer flag B_DIRTY and don't abuse B_DELWRI.
  B_DIRTY buffers are still written too late, as broken in the previous
  fix.  This is fairly harmless, because B_DIRTY is only used for
  bitmap buffers and fsck.ext2 can fix up the bitmaps perfectly.
  
  Fixed a race in ULCK_BUF() (bremfree() was outside of the splbio()
  section).
