Subject: [PATCH] 2.6.16-rc-mm4 reiser4 calls try_to_unmap() with 1 arg -- now takes 2
Date: Thu, 02 Feb 2006 15:16:15 -0500	[thread overview]
Message-ID: <1138911375.5204.31.camel@localhost.localdomain> (raw)

Apparent race between reiser4 and direct migration patches in 16-rc1-
mm4.
Direct migration added arg to rmap.c:try_to_unmap()--int ignore_refs--
and
fixed up existing refs.  reiser4 adds new call with single arg. 

One doesn't see this when building mm4 w/ reiser4 because the ref under
an
"#if REISER4_COPY_ON_CAPTURE" that is apparently not enabled.  I  just
noticed
it while looking at direct migration patches.  So, this patch is
essentially
UNTESTED.  Supplied simply to illustrate the location of the single arg
ref.
