From 8932c2e0dcae52e73430878fd8a7a7800176eada Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 26 Jun 2006 00:27:36 -0700 Subject: [PATCH] md: remove arbitrary limit on chunk size The largest chunk size the code can support without substantial surgery is 2^30 bytes, so make that the limit instead of an arbitrary 4Meg. Some day, the 'chunksize' should change to a sector-shift instead of a byte-count. Then no limit would be needed.
