However, the rollback itself can also fail in which case\nanother migration will be erroneously performed. Besides the fact that\nthis ping pong is not a very good idea, it also creates a problem.\n\nEach virtual chunk references two chunks: The currently used one\n('vchunk->chunk') and a backup ('vchunk->chunk2'). During migration the\nfirst holds the chunk we want to migrate filters to and the second holds\nthe chunk we are migrating filters from.\n\nThe code currently assumes - but does not verify - that the backup chunk\ndoes not exist (NULL) if the currently used chunk does not reference the\ntarget region. This assumption breaks when we are trying to rollback a\nrollback, resulting in the backup chunk being overwritten and leaked\n[1].\n\nFix by not rolling back a failed rollback and add a warning to avoid\nfuture cases.\n\n[1]\nWARNING: CPU: 5 PID: 1063 at lib/parman.c:291 parman_destroy+0x17/0x20\nModules linked in:\nCPU: 5 PID: 1063 Comm: kworker/5:11 Tainted: G        W          6.9.0-rc2-custom-00784-gc6a05c468a0b #14\nHardware name: Mellanox Technologies Ltd.
