The patch titled
dm: fix block device initialisation
has been removed from the -mm tree. Its filename is
dm-fix-block-device-initialisation.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: dm: fix block device initialisation
From: Jeff Mahoney <jeffm@xxxxxxxx>
In alloc_dev(), we register the device with the block layer and then continue
to initialize the device. But register_disk() makes the device available to
be opened before we have completed initialising it.
This patch moves the final bits of the initialization above the disk
registration.
[akpm: too late for 2.6.17 - suitable for 2.6.17.x after it has settled]
