The patch titled
dm mirror log: bitset_size fix
has been removed from the -mm tree. Its filename is
dm-mirror-log-bitset_size-fix.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: dm mirror log: bitset_size fix
From: Alasdair G Kergon <agk@xxxxxxxxxx>
Fix the 'sizeof' in the region log bitmap size calculation: it's uint32_t, not
unsigned long - this breaks on some archs.
