2013-07-08[SCSI] qla2xxx: Do not query FC statistics during chip reset.Chad Dupuis1-1/+4
During a chip reset, the mailbox call to get FC statistics from the ISP will not work resulting in needless mailbox accesses and errors printing out: qla2xxx [0000:05:00.0]-00af:11: Performing ISP error recovery - ha=ffff881fad044800. qla2xxx [0000:05:00.0]-1020:11: **** Failed mbx[0]=4001, mb[1]=4953, mb[2]=5020, mb[3]=b100, cmd=6d ****. qla2xxx [0000:05:00.0]-1020:11: **** Failed mbx[0]=4001, mb[1]=4953, mb[2]=5020, mb[3]=b100, cmd=6d ****. qla2xxx [0000:05:00.0]-1020:11: **** Failed mbx[0]=4001, mb[1]=4953, mb[2]=5020, mb[3]=b100, cmd=6d ****. qla2xxx [0000:05:00.0]-1020:11: **** Failed mbx[0]=4001, mb[1]=4953, mb[2]=5020, mb[3]=b100, cmd=6d ****. qla2xxx [0000:05:00.0]-1020:11: **** Failed mbx[0]=4001, mb[1]=4953, mb[2]=5020, mb[3]=b100, cmd=6d ****.

This change updates the ti-soc-thermal driver to use standard GPIO DT bindings to read the GPIO number associated to thermal shutdown IRQ, in case the device features it. Previously, the code was using a specific DT bindings. As now OMAP supports the standard way to model GPIOs, there is no point in having a ti specific binding.

2013-07-08locks: move file_lock_list to a set of percpu hlist_heads and convert ↵Jeff Layton2-20/+50
file_lock_lock to an lglock The file_lock_list is only used for /proc/locks. The vastly common case is for locks to be put onto the list and come off again, without ever being traversed. Help optimize for this use-case by moving to percpu hlist_head-s. At the same time, we can make the locking less contentious by moving to an lglock. When iterating over the lists for /proc/locks, we must take the global lock and then iterate over each CPU's list in turn. This change necessitates a new fl_link_cpu field to keep track of which CPU the entry is on. On x86_64 at least, this field is placed within an existing hole in the struct to avoid growing the size.

2013-07-079P: Add cancelled() to the transport functions.Simon Derr3-3/+23
RDMA needs to post a buffer for each incoming reply. Hence it needs to keep count of these and needs to be aware of whether a flushed request has received a reply or not. This patch adds the cancelled() callback to the transport modules. It is called when RFLUSH has been received and that the corresponding request will never receive a reply.

2013-07-079P/RDMA: Use a semaphore to protect the RQSimon Derr1-10/+12
The current code keeps track of the number of buffers posted in the RQ, and will prevent it from overflowing. But it does so by simply dropping post requests (And leaking memory in the process). When this happens there will actually be too few buffers posted, and soon the 9P server will complain about 'RNR retry counter exceeded' errors. Instead, use a semaphore, and block until the RQ is ready for another buffer to be posted. Signed-off-by: Simon Derr <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>

2013-07-079P: Fix fcall allocation for rdmaSimon Derr1-16/+23
The current code assumes that when a request in the request array does have a tc, it also has a rc. This is normally true, but not always : when using RDMA, req->rc will temporarily be set to NULL after the request has been sent. That is usually OK though, as when the reply arrives, req->rc will be reassigned to a sane value before the request is recycled. But there is a catch : if the request is flushed, the reply will never arrive, and req->rc will be NULL, but not req->tc. This patch fixes p9_tag_alloc to take this into account.

2013-07-07fs/9p: xattr: add trusted and security namespacesJim Garlick6-1/+182
Allow requests for security.* and trusted.* xattr name spaces to pass through to server. The new files are 99% cut and paste from fs/9p/xattr_user.c with the namespaces changed. It has the intended effect in superficial testing. I do not know much detail about how these namespaces are used, but passing them through to the server, which can decide whether to handle them or not, seems reasonable. I want to support a use case where an ext4 file system is mounted via 9P, then re-exported via samba to windows clients in a cluster. Windows wants to store xattrs such as security.NTACL. This works when ext4 directly backs samba, but not when 9P is inserted.
