On\ncompletion of a request, the next one is queued; however, block layer\nmust not implicitly call into q-\u003erequest_fn() directly from completion\npath. This makes the queue behave unexpectedly when seen from the\ndrivers and violates the assumption that q-\u003erequest_fn() is called\nwith process context + queue_lock.\n\nThis patch makes blk-flush the following two changes to make sure\nq-\u003erequest_fn() is not called directly from request completion path.\n\n- blk_flush_complete_seq_end_io() now asks __blk_run_queue() to always\n use kblockd instead of calling directly into q-\u003erequest_fn().\n\n- queue_next_fseq() uses ELEVATOR_INSERT_REQUEUE instead of\n ELEVATOR_INSERT_FRONT so that elv_insert() doesn\u0027t try to unplug the\n request queue directly.\n\nReported by Jan in the following threads.\n\n http://thread.gmane.org/gmane.linux.ide/48778\n http://thread.gmane.org/gmane.linux.ide/48786\n\nstable: applicable to v2.6.37.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReported-by: Jan Beulich \u003cJBeulich@novell.com\u003e\nCc: \"David S.
