Subject: [PATCH] md SET_BITMAP_FILE compat ioctl
Date: Fri, 22 Sep 2006 11:29:18 -0400 [thread overview]
Message-ID: <4514014E.1060302@steeleye.com> (raw)
In-Reply-To: <4512F55D.5030907@steeleye.com>
[-- Attachment #1: Type: text/plain, Size: 328 bytes --]
The SET_BITMAP_FILE ioctl currently doesn't have a compat entry, so on
64-bit systems a 32-bit mdadm will fail:
Sep 20 16:34:52 caspian kernel: ioctl32(mdadm:8056): Unknown cmd fd(3)
cmd(8004092b){00} arg(00000004) on /dev/md0
The fix is to build a 64-bit mdadm or apply the following patch (compile
tested only).
