  "message": "[PATCH] dm: fix find_device race\n\nThere is a race between dev_create() and find_device().\n\nIf the mdptr has not yet been stored against a device, find_device() needs to\nbehave as though no device was found.  It already returns NULL, but there is a\ndm_put() missing: it must drop the reference dm_get_md() took.\n\nThe bug was introduced by dm-fix-mapped-device-ref-counting.patch.\n\nIt manifests itself if another dm ioctl attempts to reference a newly-created\ndevice while the device creation ioctl is still running.  The consequence is\nthat the device cannot be removed until the machine is rebooted.  Certain udev\nconfigurations can lead to this happening.\n\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\nCc: \u003cdm-devel@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
