  "message": "[PATCH] dm: prevent removal if open\n\nIf you misuse the device-mapper interface (or there\u0027s a bug in your userspace\ntools) it\u0027s possible to end up with \u0027unlinked\u0027 mapped devices that cannot be\nremoved until you reboot (along with uninterruptible processes).\n\nThis patch prevents you from removing a device that is still open.\n\nIt introduces dm_lock_for_deletion() which is called when a device is about to\nbe removed to ensure that nothing has it open and nothing further can open it.\n It uses a private open_count for this which also lets us remove one of the\nproblematic bdget_disk() calls elsewhere.\n\nSigned-off-by: Alasdair G Kergon \u003cagk@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
