Subject: [PATCH 09/35] btrfs: update __btrfs_map_block for bi_op transition
Date: Tue, 5 Jan 2016 14:53:12 -0600 [thread overview]
Message-ID: <1452027218-32303-10-git-send-email-mchristi@redhat.com> (raw)
In-Reply-To: <1452027218-32303-1-git-send-email-mchristi@redhat.com>
From: Mike Christie <mchristi@redhat.com>
We no longer pass in a bitmap of rq_flag_bits bits
to __btrfs_map_block. It will always be a REQ_OP,
or the btrfs specific REQ_GET_READ_MIRRORS,
so this drops the bit tests.
