Public bug reported: I have a block device exported from zfs, and from time to time it drops off the network, after which operations such as targetctl restore will hang.
When it hangs it is stuck in core_tpg_del_initiator_node_acl: ``` [<0>] core_tpg_del_initiator_node_acl+0x8e/0x120 [target_core_mod] [<0>] target_fabric_nacl_base_release+0x26/0x30 [target_core_mod] [<0>] config_item_release+0x5d/0xd0 [<0>] config_item_put+0x27/0x30 [<0>] configfs_rmdir+0x1c5/0x300 [<0>] vfs_rmdir+0x86/0x1a0 [<0>] do_rmdir+0x18c/0x1c0 [<0>] __x64_sys_rmdir+0x17/0x20 [<0>] do_syscall_64+0x57/0x190 [<0>] entry_SYSCALL_64_after_hwframe+0x44/0xa9 ``` I can see there have been many similar bugs over the years...
