  "message": "drbd: fix potential spinlock deadlock\n\ndrbd_try_clear_on_disk_bm() has a sanity check for the number of blocks\nleft to be resynced (rs_left) in the current resync extent.\nIf it detects a mismatch, it complains, and forces a disconnect using\ndrbd_force_state(mdev, NS(conn, C_DISCONNECTING));\n\nUnfortunately, this may be called while holding the req_lock,\nand drbd_force_state() want\u0027s to aquire that lock itself. Deadlock.\n\nDon\u0027t force a disconnect, but fix up rs_left by recounting and\nreassigning the number of dirty blocks in that extent.\n\nSigned-off-by: Philipp Reisner \u003cphilipp.reisner@linbit.com\u003e\nSigned-off-by: Lars Ellenberg \u003clars.ellenberg@linbit.com\u003e\n",
