If a REQ_ATOMIC write encounters a\nbadblock within the requested range, the code jumps to err_handle\nwithout dropping the reference taken for the current mirror.\n\nerr_handle\u0027s cleanup loop will only decrements for k \u003c i and\nr1_bio-\u003ebios[k] is non-NULL. The current slot is therefore skipped,\nleaving its nr_pending reference leaked permanently. The reference\nprevents the rdev from ever being removed, since raid1_remove_conf()\nrefuses to remove an rdev with nr_pending \u003e 0.\n\nFix this by calling rdev_dec_pending() before jumping to err_handle."
