2012-01-05netdev: FCoE: Add new ndo_get_fcoe_hbainfo() callNeerav Parikh
This adds a new ndo_get_fcoe_hbainfo() call in net_device_ops for FCoE protocol stack. If supported by the underlying device, the FCoE protocol stack will call this to get device specific information from the underlying device. This information will then be utilized by the FCoE protocol stack to register Fiber Channel HBA attributes with the Fiber Channel Management Service via Fabric Device Management Interface (FDMI) as per the T11 FC-GS specification. Changes in v2: - As per comments from David Miller aligning the parameters of the ndo_get_fcoe_hbainfo() Signed-off-by: Neerav Parikh <Neerav.Parikh@intel.com> Tested-by: Ross Brattain <ross.b.brattain@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: David S.

2012-01-05NFS: Cache state owners after files are closedChuck Lever
Servers have a finite amount of memory to store NFSv4 open and lock owners. Moreover, servers may have a difficult time determining when they can reap their state owner table, thanks to gray areas in the NFSv4 protocol specification. Thus clients should be careful to reuse state owners when possible. Currently Linux is not too careful. When a user has closed all her files on one mount point, the state owner's reference count goes to zero, and it is released. The next OPEN allocates a new one. A workload that serially opens and closes files can run through a large number of open owners this way. When a state owner's reference count goes to zero, slap it onto a free list for that nfs_server, with an expiry time. Garbage collect before looking for a state owner. This makes state owners for active users available for re-use. Now that there can be unused state owners remaining at umount time, purge the state owner free list when a server is destroyed. Also be sure not to reclaim unused state owners during state recovery. This change has benefits for the client as well. For some workloads, this approach drops the number of OPEN_CONFIRM calls from the same as the number of OPEN calls, down to just one. This reduces wire traffic and thus open(2) latency. Before this patch, untarring a kernel source tarball shows the OPEN_CONFIRM call counter steadily increasing through the test. With the patch, the OPEN_CONFIRM count remains at 1 throughout the entire untar. As long as the expiry time is kept short, I don't think garbage collection should be terribly expensive, although it does bounce the clp->cl_lock around a bit. [ At some point we should rationalize the use of the nfs_server ->destroy method. ] Signed-off-by: Chuck Lever <chuck.lever@oracle.com> [Trond: Fixed a garbage collection race and a few efficiency issues] Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2012-01-05NFSv4: include bitmap in nfsv4 get acl dataAndy Adamson
The NFSv4 bitmap size is unbounded: a server can return an arbitrary sized bitmap in an FATTR4_WORD0_ACL request. Replace using the nfs4_fattr_bitmap_maxsz as a guess to the maximum bitmask returned by a server with the inclusion of the bitmap (xdr length plus bitmasks) and the acl data xdr length to the (cached) acl page data. This is a general solution to commit e5012d1f "NFSv4.1: update nfs4_fattr_bitmap_maxsz" and fixes hitting a BUG_ON in xdr_shrink_bufhead when getting ACLs. Fix a bug in decode_getacl that returned -EINVAL on ACLs > page when getxattr was called with a NULL buffer, preventing ACL > PAGE_SIZE from being retrieved.

2012-01-04usb: ch9: fix up MaxStreams helperFelipe Balbi
According to USB 3.0 Specification Table 9-22, if bmAttributes [4:0] are set to zero, it means "no streams supported", but the way this helper was defined on Linux, we will *always* have one stream which might cause several problems. For example on DWC3, we would tell the controller endpoint has streams enabled and yet start transfers with Stream ID set to 0, which would goof up the host side. While doing that, convert the macro to an inline function due to the different checks we now need.

2012-01-04driver core: remove __must_check from device_create_fileGreg Kroah-Hartman
With the conversion of the sysdev to a real struct device, more drivers are calling device_create_file, and some of them don't check the return value, which isn't wise. But as they happen to be in parts of the kernel where a warning is considered an error (i.e. powerpc), this breaks the build. So for now, remove the marking on the function, which fixes the build problems.

2012-01-04ethtool: Allow drivers to select RX NFC rule locationsBen Hutchings
Define special location values for RX NFC that request the driver to select the actual rule location. This allows for implementation on devices that use hash-based filter lookup, whereas currently the API is more suited to devices with TCAM lookup or linear search. In ethtool_set_rxnfc() and the compat wrapper ethtool_ioctl(), copy the structure back to user-space after insertion so that the actual location is returned.

2012-01-04dlm: add recovery callbacksDavid Teigland
These new callbacks notify the dlm user about lock recovery. GFS2, and possibly others, need to be aware of when the dlm will be doing lock recovery for a failed lockspace member. In the past, this coordination has been done between dlm and file system daemons in userspace, which then direct their kernel counterparts. These callbacks allow the same coordination directly, and more simply. Signed-off-by: David Teigland <teigland@redhat.com>
