wireless: add back sysfs directory

2012-11-16T20:37:52+00:00

commit 35b2a113cb0298d4f9a1263338b456094a414057 broke (at least)
Fedora's networking scripts, they check for the existence of the
wireless directory. As the files aren't used, add the directory
back and not the files. Also do it for both drivers based on the
old wireless extensions and cfg80211, regardless of whether the
compat code for wext is built into cfg80211 or not.

net: add unknown state to sysfs NIC duplex export

2012-09-05T21:40:07+00:00

Currently when the NIC duplex state is DUPLEX_UNKNOWN it is exported as
full through sysfs, this patch adds support for DUPLEX_UNKNOWN. It is
handled the same way as in ethtool.

wireless: remove wext sysfs

2012-06-05T19:32:15+00:00

The only user of this was hal prior to its 0.5.12
release which happened over two years ago, so I'm
sure this can be removed without issues.

static keys: Introduce 'struct static_key', static_key_true()/false() and static_key_slow_[inc|dec]()

2012-02-24T09:05:59+00:00

So here's a boot tested patch on top of Jason's series that does
all the cleanups I talked about and turns jump labels into a
more intuitive to use facility. It should also address the
various misconceptions and confusions that surround jump labels.

Typical usage scenarios:

        #include 

        struct static_key key = STATIC_KEY_INIT_TRUE;

        if (static_key_false(&key))
                do unlikely code
        else
                do likely code

Or:

        if (static_key_true(&key))
                do likely code
        else
                do unlikely code

The static key is modified via:

        static_key_slow_inc(&key);
        ...
        static_key_slow_dec(&key);

The 'slow' prefix makes it abundantly clear that this is an
expensive operation.

I've updated all in-kernel code to use this everywhere. Note
that I (intentionally) have not pushed through the rename
blindly through to the lowest levels: the actual jump-label
patching arch facility should be named like that, so we want to
decouple jump labels from the static-key facility a bit.

On non-jump-label enabled architectures static keys default to
likely()/unlikely() branches.

bql: Fix inconsistency between file mode and attr method.

2012-01-17T15:05:55+00:00

There is no store() method for inflight attribute in the
tx-/byte_queue_limits sysfs directory.
So remove S_IWUSR bit.

net: reintroduce missing rcu_assign_pointer() calls

2012-01-12T20:26:56+00:00

commit a9b3cd7f32 (rcu: convert uses of rcu_assign_pointer(x, NULL) to
RCU_INIT_POINTER) did a lot of incorrect changes, since it did a
complete conversion of rcu_assign_pointer(x, y) to RCU_INIT_POINTER(x,
y).

We miss needed barriers, even on x86, when y is not NULL.

2011-12-24T21:13:27+00:00

Aim of this patch is to provide full range of rps_flow_cnt on 64bit arches.

Theorical limit on number of flows is 2^32
