fs/block_dev.c: remove #if 0'ed code
Commit b2e895dbd80c420bfc0937c3729b4afe073b3848 #if 0'ed this code stating: <-- snip --> [PATCH] revert blockdev direct io back to 2.6.19 version Andrew Vasquez is reporting as-iosched oopses and a 65% throughput slowdown due to the recent special-casing of direct-io against blockdevs. We don't know why either of these things are occurring. The patch minimally reverts us back to the 2.6.19 code for a 2.6.20 release. <-- snip --> It has since been dead code, and unless someone wants to revive it now it's time to remove it. This patch also makes bio_release_pages() static again and removes the ki_bio_count member from struct kiocb, reverting changes that had been done for this dead code.
