2011-07-12netdevice: Kill 'feature' test macros.David S. Miller
Almost all of these have long outstayed their welcome. And for every one of these macros, there are 10 features for which we didn't add macros. Let's just delete them all, and get out of habit of doing things this way. Signed-off-by: David S.

2011-07-12cifs: Fix signing failure when server mandates signing for NTLMSSPShirish Pargaonkar
When using NTLMSSP authentication mechanism, if server mandates signing, keep the flags in type 3 messages of the NTLMSSP exchange same as in type 1 messages (i.e. keep the indicated capabilities same). Some of the servers such as Samba, expect the flags such as Negotiate_Key_Exchange in type 3 message of NTLMSSP exchange as well. Some servers like Windows do not. https://bugzilla.samba.org/show_bug.cgi?id=8212 Signed-off-by: Shirish Pargaonkar <shirishpargaonkar@gmail> Acked-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2011-07-12NFS: Clean up nfs_read_rpcsetup and nfs_write_rpcsetupTrond Myklebust

2011-07-12NFS: Don't use DATA_SYNC writesTrond Myklebust
If we're writing back data, and the FLUSH_STABLE flag is set, then we always want to use NFS_FILE_SYNC, since we're always in a situation where we're doing page reclaim, and so we want to free up the page as quickly as possible. If we're in the FLUSH_COND_STABLE case, then we either want to use another unstable write (if we have to do a commit anyway) or again, we want to use NFS_FILE_SYNC because we know that we have no more pages to write out.

2011-07-12NFSv4.1: Clean ups for the device id cacheTrond Myklebust
The fact that the global device id cache holds a reference to the nfs4_deviceid_node until it is invisible to rcu lookups implies that we can always assume that the reference count is non-zero in _find_get_deviceid.

2011-07-12NFS: Cleanup of the nfs_pageio code in preparation for a pnfs bugfixTrond Myklebust
We need to ensure that the layouts are set up before we can decide to coalesce requests.

This patch cleans up the existing callback methods before adding the 'initialisation' callback. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2011-07-12NFS: pnfs: loop over multipath addrs on connectWeston Andros Adamson
Don't just use the first addr in the multipath list - instead, loop over addresses when calling nfs4_set_ds_client() (which calls connect) until it is successful. Although this is not real multipath support, it's a quick fix to handle when an MDS sends a list of addresses for a DS and some of the addr families are unsupported or misconfigured (like no routable ipv6 addr assigned). This will attempt all paths to the DS before giving up, instead of immediately falling back to the MDS. As before, an error encountered after a successful connect() will cause all i/o to fall back to the MDS.

This patch gives M-Audio Fast Track Pro and M-Audio Quattro quirks and endpoints to boot and setup those devices with special options (digital inputs and outputs, 24 bits mode, etc...). M-Audio Audiophile quirks are just adapted to match the new global M-Audio parameters. Special configurations can be then loaded through a modprobe conf file.

2011-07-12drm/i915: Clean up i915_driver_load failure pathKeith Packard
i915_driver_load adds a write-combining MTRR region for the GTT aperture to improve memory speeds through the aperture. If i915_driver_load fails after this, it would not have cleaned up the MTRR. This shouldn't cause any problems, except for consuming an MTRR register. Still, it's best to clean up completely in the failure path, which is easily done by calling mtrr_del if the mtrr was successfully allocated. i915_driver_load calls i915_gem_load which register i915_gem_inactive_shrink. If i915_driver_load fails after calling i915_gem_load, the shrinker will be left registered. When called, it will access freed memory and crash. The fix is to unregister the shrinker in the failure path using code duplicated from i915_driver_unload. i915_driver_load also has some incorrect gotos in the error cleanup paths: * After failing to initialize the GTT (which cannot happen, btw, intel_gtt_get returns a fixed (non-NULL) value), it tries to free the uninitialized WC IO mapping.
