  2. Real Data Corruption Under ext2 In The Stable
     And Unstable Kernels, And A Fix

     21 Mar - 27 Mar (4 posts): ext2fs bug : files are disapeared,
     unable to delete, two files' contents are switched etc. 

  Soohoon Lee reported serious data corruption with ext2,
  in cases of low memory and frequent file creation and
  deletion operations. He explained that under those
  conditions, files would spontaneously disappear or be
  undeletable, the contents of two files would spontaneously
  switch, and fsck would find inconsistancies in properly
  unmounted filesystems. He posted a one-line patch to
  fs/ext2/namei.c to fix it; and Theodore Y Ts'o confirmed
  that this was indeed a problem, and not just some local
  glitch. In response to Soohoon's patch, Ted replied,
  "This apparently solves the problem for Linux 2.2,
  but I'd prefer a cleaner patch for Linux 2.3. Enclosed
  find the patch, which I will be sending on to Linus.
  I haven't had a chance to backport this patch to Linux
  2.2 yet, but it shoudl be relatively simple." He posted
  his patch, which was much longer than Soohoon's, and there
  was some talk about other changes to make to fs/ext2/namei.c,
  if they were going to be changing it at all. 

Podobne symptomy sa tu uz spominali viackrat, komu sa to
stava, dohladajte si ten patch v l-k archive.

Zdravi
