From ff01bb4832651c6d25ac509a06a10fcbd75c461c Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 16 Sep 2011 02:31:11 -0400 Subject: fs: move code out of buffer.c Move invalidate_bdev, block_sync_page into fs/block_dev.c. Export kill_bdev as well, so brd doesn't have to open code it. Reduce buffer_head.h requirement accordingly. Removed a rather large comment from invalidate_bdev, as it looked a bit obsolete to bother moving. The small comment replacing it says enough.
