Works fine for me. Thank you! However I noticed another recursive call while dumping all call traces: ... [<00000000001e1952>] zfcp_scsi_command_async+0xf6/0x1c4 [<000000000013cd6a>] scsi_dispatch_cmd+0x1ae/0x37c [<0000000000143dc4>] scsi_request_fn+0x1dc/0x390 [<000000000012f65a>] generic_unplug_device+0x2a/0x38 [<0000000000181262>] dm_table_unplug_all+0x42/0x58 [<000000000017e598>] dm_unplug_all+0x2c/0x44 [<0000000000181262>] dm_table_unplug_all+0x42/0x58 [<000000000017e598>] dm_unplug_all+0x2c/0x44 [<00000000000782aa>] block_sync_page+0x4e/0x68 [<00000000000514f8>] sync_page+0x48/0x68 [<00000000002ab36e>] __wait_on_bit+0x9a/0xe0 ... Even though there is a lot of space left on the stack (this time) I don't think it's desirable to have recursive calls. Especially not when going for 4k stacks.
