Yufen Yu d11de63f2b nvme-loop: init nvmet_ctrl fatal_err_work when allocate ... After commit 4d43d395fe (workqueue: Try to catch flush_work() without INIT_WORK()), it can cause warning when delete nvme-loop device, trace like: [ 76.601272] Call Trace: [ 76.601646] ? del_timer+0x72/0xa0 [ 76.602156] __cancel_work_timer+0x1ae/0x270 [ 76.602791] cancel_work_sync+0x14/0x20 [ 76.603407] nvmet_ctrl_free+0x1b7/0x2f0 [nvmet] [ 76.604091] ? free_percpu+0x168/0x300 [ 76.604652] nvmet_sq_destroy+0x106/0x240 [nvmet] [ 76.605346] nvme_loop_destroy_admin_queue+0x30/0x60 [nvme_loop] [ 76.606220] nvme_loop_shutdown_ctrl+0xc3/0xf0 [nvme_loop] [ 76.607026] nvme_loop_delete_ctrl_host+0x19/0x30 [nvme_loop] [ 76.607871] nvme_do_delete_ctrl+0x75/0xb0 [ 76.608477] nvme_sysfs_delete+0x7d/0xc0 [ 76.609057] dev_attr_store+0x24/0x40 [ 76.609603] sysfs_kf_write+0x4c/0x60 [ 76.610144] kernfs_fop_write+0x19a/0x260 [ 76.610742] __vfs_write+0x1c/0x60 [ 76.611246] vfs_write+0xfa/0x280 [ 76.611739] ksys_write+0x6e/0x120 [ 76.612238] __x64_sys_write+0x1e/0x30 [ 76.612787] do_syscall_64+0xbf/0x3a0 [ 76.613329] entry_SYSCALL_64_after_hwframe+0x44/0xa9 We fix it by moving fatal_err_work init to nvmet_alloc_ctrl(), which may more reasonable.
