From 29121bd0b00ebb9524971a583fea4a2f7afe8041 Mon Sep 17 00:00:00 2001 From: Alasdair G Kergon Date: Mon, 26 Jun 2006 00:27:29 -0700 Subject: [PATCH] [PATCH] dm mirror log: bitset_size fix Fix the 'sizeof' in the region log bitmap size calculation: it's uint32_t, not unsigned long - this breaks on some archs.
