Pull second vfs pile from Al Viro:
"The stuff in there: fsfreeze deadlock fixes by Jan (essentially, the
deadlock reproduced by xfstests 068), symlink and hardlink restriction
patches, plus assorted cleanups and fixes.
Note that another fsfreeze deadlock (emergency thaw one) is *not*
dealt with - the series by Fernando conflicts a lot with Jan's, breaks
userland ABI (FIFREEZE semantics gets changed) and trades the deadlock
for massive vfsmount leak; this is going to be handled next cycle.
There probably will be another pull request, but that stuff won't be
in it."

Here's the big staging tree merge for the 3.6-rc1 merge window.
There are some patches in here outside of drivers/staging/, notibly the iio
code (which is still stradeling the staging / not staging boundry), the pstore
code, and the tracing code. All of these have gotten ackes from the various
subsystem maintainers to be included in this tree. The pstore and tracing
patches are related, and are coming here as they replace one of the android
staging drivers.
Otherwise, the normal staging mess. Lots of cleanups and a few new drivers
(some iio drivers, and the large csr wireless driver abomination.)
Note, you will get a merge issue with the following files:
drivers/staging/comedi/drivers/s626.h
drivers/staging/gdm72xx/netlink_k.c
both of which should be trivial for you to handle.

This patch adds the following structure:
struct netlink_kernel_cfg {
unsigned int groups;
void (*input)(struct sk_buff *skb);
struct mutex *cb_mutex;
};
That can be passed to netlink_kernel_create to set optional configurations
for netlink kernel sockets.
I've populated this structure by looking for NULL and zero parameters at the
existing code. The remaining parameters that always need to be set are still
left in the original interface.
That includes optional parameters for the netlink socket creation. This allows
easy extensibility of this interface in the future.
This patch also adapts all callers to use this new interface.

The caif_hsi.c, on the other hand, was not. It's a conflict between

device with ops structure.") in the net-next tree and commit
39abbaef19 ("caif-hsi: Postpone init of

The NLMSG_PUT() macro contains a hidden goto that jumps to the
nlmsg_failure label. Since the sk_buff was allocated before the macro,
jumping to the nlmsg_failure label leaks the memory allocated for it.
Calling kfree() before returning would fix it, but is better to avoid
using this error prone macro and use nlmsg_put() instead.
Also, use nlmsg_data() instead of NLMSG_DATA() to check type.
