If discard reuses an\nr10bio that was previously used for a read, read_slot can still be\nnon-negative, and discard cleanup can skip bio_put() on repl_bio.\n\nReset read_slot to -1 when preparing an r10bio for discard so the\nreplacement bio is always released correctly.","state":0,"publishedAt":"2026-08-15T05:58:55.023+00:00","modifiedAt":"2026-10-16T18:55:36.173+00:00","affected":[{"ecosystem":"Vendor
