Hi!
Is this patch from 030213 it needed by anyone using ReiserFS within
2.4.20 and 2.4.21-preX ?
What is "DIRECT IO" with reiserfs from the topic line of the patch:
"# reiserfs: Fix DIRECT IO interference with tail packing" ?
Thanks for the info and best regards,
Manuel
(I hope I didn't miss any hidden announcement...)

It fixes a bug where a recently unpacked tail might race to the disk
with bytes modified via DIRECT IO. The common way to trigger the bug is
via a mixture of direct io and regular file access at the same time.
Most people won't see the bug, since it is uncommon to mix regular and
direct io that way.
