      tmpfs: fix regression hang in fallocate undo · 7f556567
      Hugh Dickins authored
      The well-spotted fallocate undo fix is good in most cases, but not when
      fallocate failed on the very first page.  index 0 then passes lend -1
      to shmem_undo_range(), and that has two bad effects: (a) that it will
      undo every fallocation throughout the file, unrestricted by the current
      range; but more importantly (b) it can cause the undo to hang, because
      lend -1 is treated as truncation, which makes it keep on retrying until
      every page has gone, but those already fully instantiated will never go
      away.  Big thank you to xfstests generic/269 which demonstrates this.
