From 87d7c8aca8670a772f74766c19e0345a606b67a9 Mon Sep 17 00:00:00 2001 From: Jason Baron Date: Fri, 29 Sep 2006 02:01:01 -0700 Subject: [PATCH] block_dev.c mutex_lock_nested() fix In the case below we are locking the whole disk not a partition. This change simply brings the code in line with the piece above where when we are the 'first' opener, and we are a partition.
