479f6ea85e [PATCH] USB: fix hid core to return proper error code from probe
Drivers need to return -ENODEV when they can't bind to a device.
Anything else stops the "bind a device to a driver" search.

b7c84c6ada [PATCH] boot_pageset must not be freed.
The boot_pageset needs to be preserved for hotplugging and for off line
processors and nodes. Otherwise pointers will point into memory that has
now a different use. /proc/zoneinfo is currently showing strange results
if processors / nodes are not present.

NFSv3 currently returns the unsigned 64-bit cookie directly to
 userspace. The following patch causes the kernel to generate
 loff_t offsets for the benefit of userland.
 The current server-generated READDIR cookie is cached in the
 nfs_open_context instead of in filp->f_pos, so we still end up work
 correctly under directory insertions/deletion.

ae3884621b [PATCH] RPC: kick off socket connect operations faster
Make the socket transport kick the event queue to start socket connects
 immediately.  This should improve responsiveness of applications that are
 sensitive to slow mount operations (like automounters).

 We are now also careful to cancel the connect worker before destroying
 the xprt.  This eliminates a race where xprt_destroy can finish before
 the connect worker is even allowed to run.

 Test-plan:
 Destructive testing (unplugging the network temporarily).  Connectathon
 with UDP and TCP.  Hard-code impossibly small connect timeout.

055ffbea05 [PATCH] NFS: Fix handling of the umask when an NFSv3 default acl is present.
NFSv3 has no concept of a umask on the server side: The client applies
 the umask locally, and sends the effective permissions to the server.
 This behavior is wrong when files are created in a directory that has a
 default ACL.  In this case, the umask is supposed to be ignored, and
 only the default ACL determines the file's effective permissions.

 Usually its the server's task to conditionally apply the umask.  But
 since the server knows nothing about the umask, we have to do it on the
 client side.  This patch tries to fetch the parent directory's default
 ACL before creating a new file, computes the appropriate create mode to
 send to the server, and finally sets the new file's access and default
 acl appropriately.

 Many thanks to Buck Huppmann <buchk@pobox.com> for sending the initial
 version of this patch, as well as for arguing why we need this change.
