Yes, why not, I am only wondering why loopback / dummy (and others ?)
only set NETIF_F_TSO :)

Since I want to play with ECN, I might also add NETIF_F_TSO_ECN ;)

For other flags, I really doubt it can matter on ifb ?

[PATCH v3 net-next-2.6] ifb: add performance flags

IFB can use the full set of features flags (NETIF_F_SG |
NETIF_F_FRAGLIST | NETIF_F_TSO | NETIF_F_NO_CSUM | NETIF_F_HIGHDMA) to
avoid unnecessary split of some packets (GRO for example)

Changli suggested to also set vlan_features, NETIF_F_TSO6,
NETIF_F_TSO_ECN.

Jarek suggested to add NETIF_F_HW_VLAN_TX as well.

libata: issue DIPM enable commands with LPM state updated

Low level drivers may behave differently depending on the current
link->lpm_policy.  During ata_eh_set_lpm(), DIPM enable commands are
issued after the successful completion of ap->ops->set_lpm(), which
means that the controller is already in the target state.  This causes
DIPM enable commands to be processed with mismatching controller power
state and link->lpm_policy value.

In ahci, link->lpm_policy is used to ignore certain PHY events if LPM
is enabled; however, as DIPM commands are issued with stale
link->lpm_policy, they sometimes end up triggering these conditions
and get aborted leading to LPM configuration failure.

Fix it by updating link->lpm_policy before issuing DIPM enable
commands.

      rtc@68 {
        compatible = "dallas,ds1337";
        reg = <0x68>;
      };

of_i2c_register_devices() will try to load a module called ds1337.ko.
There is no such module, so it will fail.  If we look in modules.alias
we will find entries like these:

.
.
.
alias i2c:ds1339 rtc_ds1307
alias i2c:ds1338 rtc_ds1307
alias i2c:ds1337 rtc_ds1307
alias i2c:ds1307 rtc_ds1307
alias i2c:ds1374 rtc_ds1374
.
.
.

The module we want is really called rtc_ds1307.ko.  If we request a
module called "i2c:ds1337", the userspace module loader will do the
right thing (unless it is busybox) and load rtc_ds1307.ko.  So we add
the I2C_MODULE_PREFIX to the request_module() string.

13 years agoKEYS: Don't call up_write() if __key_link_begin() returns an error
David Howells [Wed, 22 Dec 2010 16:24:13 +0000 (16:24 +0000)]
KEYS: Don't call up_write() if __key_link_begin() returns an error

In construct_alloc_key(), up_write() is called in the error path if
__key_link_begin() fails, but this is incorrect as __key_link_begin() only
returns with the nominated keyring locked if it returns successfully.

Without this patch, you might see the following in dmesg:
