Subject: block: set REQ_TYPE_FS on flush requests
X-Git-Tag: v2.6.36-rc1~288^2~35
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=28e18d0188b9e3ab82ebd09d9b1d1c7f8d1822aa;p=uclinux-h8%2Flinux.git

block: set REQ_TYPE_FS on flush requests

the block layer doesn't set rq->cmd_type on flush requests. By
definition, it should be REQ_TYPE_FS (the lower layers build a command
and interpret the result of it, that is, the block layer doesn't know
the details).
