Indeed, "grave" may have been too high, but then the Severity description
forgot to include the possibility of actually killing hardware, which should
be rated rather high IMHO.

I didn't know about the Sid tagging (Sid here, with a custom 2.6.11-ck8
kernel), sorry.

The LKML thread indicates that FAT sync behaviour has been changed by
Colin Leroy
(http://readlist.com/lists/vger.kernel.org/linux-kernel/22/112590.html).
The discussion thread for this patch is at
http://www.ussg.iu.edu/hypermail/linux/kernel/0411.3/0000.html

For the record, I'd like to publicly state here:
- pmount should get rid of default sync ASAP for the moment,
  in order to avoid too many killed USB sticks
- contrary to the strange belief of certain people:
  "we don't need a new sync mode",
  http://readlist.com/lists/vger.kernel.org/linux-kernel/22/112509.html)
  , I do think we want a special mount mode (if possible), to indicate
  that we want fast, but not ultra-immediate (sync) writeout of dirty buffers.
  The usual caching in async mode will take too long for people to notice
  that things aren't fully written yet (the USB flash LED will switch off
  again!), thus we need faster processing (almost constant writing without
  many dropouts would be desireable, yet not as crazy as updates on every
  single-byte change as with the sync flag).
  Plus, thinking of *manually* using "umount" or even something esoteric as
  "sync" is absolutely unthinkable for "less educated" (ahem) people
  who unplug things on a whim.
  Such a new mount flag could be called "nowritecache" or "nowritebuffer"
  to indicate that we don't want any write caching in the OS.
  But this is not a very accurate description of what we really want to have
  with USB sticks, so maybe "fastwrite" (preferred) or "instantwrite"
  or "immediatewrite" (hmm) are better.

Thanks,

Andreas Mohr
