Subject: [PATCH] BLOCK: Move __invalidate_device() to block_dev.c [try #6]
X-Git-Tag: v2.6.19-rc1~640^2~15
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=b71e8a4ce03b3098c7801ee5e6e08d1a39a226c2;p=linux-2.6-omap-h63xx.git

[PATCH] BLOCK: Move __invalidate_device() to block_dev.c [try #6]

Move __invalidate_device() from fs/inode.c to fs/block_dev.c so that it can
more easily be disabled when the block layer is disabled.
