Comment (by Yeechang Lee <ylee at pobox.com>):
For what it's worth, I've been trying out both the v3 and v4 versions of
the patch on my 0.19-fixes system (FC4 ATrpms-129; I patch the SRPM then
rebuild).
Both versions patch cleanly onto the 0.19-fixes source. Both rename the
file being truncated as 'cifsxxxx' (it's a network mount). However, I
could never get v4, which I tried first, to work right; it'd either
truncate really, really slowly (like 35K/second slowly) or not truncate at
all. v3 works great (I did modify the sleep interval between truncations
to ten seconds, not Boleslaw's two), except that the cifsxxxx files don't
ever get cleared away after reaching the point where the remainder is
smaller than the truncation size (83MB for me). Other than that, the patch
works exactly as advertised. My restricted-to-ext3 NAS is redeemed!
