From ce503f59ae899c3e75a8a1cf46f2d44c0c5b5c7c Mon Sep 17 00:00:00 2001 From: Jonathan Brassow Date: Mon, 26 Jun 2006 00:27:30 -0700 Subject: [PATCH] [PATCH] dm kcopyd: error accumulation fix kcopyd should accumulate errors - otherwise I/O failures may be ignored unintentionally. And invert 'success' (used in a future patch), using a more intuitive !(read_err || write_err).
