Since commit 6cd0b1cb87 "iwlagn: fix
hw-rfkill while the interface is down", we enable interrupts when
device is not ready to receive them. However hardware, when it is in
some inconsistent state, can generate other than rfkill interrupts
and crash the system. I can reproduce crash with "kernel BUG at
drivers/net/wireless/iwlwifi/iwl-agn.c:1010!" message, when forcing
firmware restarts.
To fix only enable rfkill interrupt when down device and after probe.
I checked patch on laptop with 5100 device, rfkill change is still
passed to user space when device is down.

We want to skip VFS applying mode for NFS. So set MS_POSIXACL always
and selectively use umask. Ideally we would want to use umask only
when we don't have inheritable ACEs set. But NFS currently don't
allow to send umask to the server. So this is best what we can do
and this is consistent with NFSv3

Hi,
In fs/nfs/proc.c::nfs_proc_symlink() we will leak memory if either
nfs_alloc_fhandle() or nfs_alloc_fattr() returns NULL but the other one
doesn't.
This patch ensures memory allocated by one when the other fails is always
released (this is safe since nfs_free_fattr() and nfs_free_fhandle() both
call kfree which deals gracefully with NULL pointers).

Instead of starting the split transaction timeout timer when any request
is submitted, start it only when the destination's ACK_PENDING has been
received. This prevents us from using a timeout that is too short, and,
if the controller's AT queue is emptying very slowly, from cancelling
a packet that has not yet been sent.

power:cpu_frequency
power:machine_suspend
The old C-state/idle accounting events:

power:power_end
Have now a replacement (but we are still keeping the old
tracepoints for compatibility):
power:cpu_idle
and
power:power_frequency
is replaced with:
power:cpu_frequency
power:machine_suspend is newly introduced.
Jean Pihet has a patch integrated into the generic layer
(kernel/power/suspend.c) which will make use of it.
