2007-11-03[SCSI] ibmvscsi: Prevent IO during partner loginRobert Jennings1-5/+14
By setting the request_limit in send_srp_login to 1 we allowed login requests to be sent to the server adapter. If this was not an initial login, but was a login after a disconnect with the server, other I/O requests could attempt to be processed before the login occured. These I/O requests would fail, sometimes resulting in filesystems getting marked read-only. To address this we can set the request_limit to 0 while doing the login and add an exception where login requests, along with task management events, are always passed to the server. There is a case where the request_limit had already reached 0 would result in all events being sent rather than returning SCSI_MLQUEUE_HOST_BUSY; this has also been fixed by this patch.

Patch 49dce689ad4ef0fd1f970ef762168e4bd46f69a3 changed the sysfs data structures for SPI in a way which broke the MMC-over-SPI host driver. This patch fixes that regression by changing the scheme used to keep from knowingly trying to use a shared bus segment, and updates the adjacent comments slightly to better explain the issue.

The pid namespace patches changed the semantics of find_task_by_pid without breaking the compile resulting in get_net_ns_by_pid doing the wrong thing. So switch to using the intended find_task_by_vpid.

2007-10-26[NET]: Marking struct pernet_operations __net_initdata was inappropriateEric W. Biederman6-9/+7
It is not safe to to place struct pernet_operations in a special section. We need struct pernet_operations to last until we call unregister_pernet_subsys. Which doesn't happen until module unload. So marking struct pernet_operations is a disaster for modules in two ways. - We discard it before we call the exit method it points to. - Because I keep struct pernet_operations on a linked list discarding it for compiled in code removes elements in the middle of a linked list and does horrible things for linked insert. So this looks safe assuming __exit_refok is not discarded for modules. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
