* 'timers-for-linus-urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
timers: Fix slack calculation for expired timers
timekeeping: Fix timezone update

commit 3bbb9ec946 (timers: Introduce the concept of timer slack for
legacy timers) does not take the case into account when the timer is
already expired. This broke wireless drivers.
The solution is not to apply slack to already expired timers.

commit 64ce4c2f (time: Clean up warp_clock()) breaks the timezone
update in a very subtle way. To avoid the direct access to timekeeping
internals it adds the timezone delta to the current time with
timespec_add_safe(). This works nicely when the timezone delta is > 0.
If timezone delta is < 0 then the wrap check in timespec_add_safe()
triggers and timespec_add_safe() returns TIME_MAX and screws up
timekeeping completely.
The comment above timespec_add_safe() says:
It's assumed that both values are valid (>= 0)
Add the timezone seconds adjustment directly.

exofs: confusion between kmap() and kmap_atomic() api
exofs: Add default address_space_operations
|
| | | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | |
| | | |
For kmap_atomic() we call kunmap_atomic() on the returned pointer.
That's different from kmap() and kunmap() and so it's easy to get them
backwards.

All vectors of address_space_operations should be initialized
by the filesystem. Add the missing parts.
This is actually an optimization, by using
__set_page_dirty_nobuffers. The default, in case of NULL,
would be __set_page_dirty_buffers which has these extar if(s).
.releasepage && .invalidatepage should both not be called
because page_private() is NULL in exofs. Put a WARN_ON if
they are called, to indicate the Kernel has changed in this
regard, if when it does.

This reverts commit 03ceedea972a82d343fa5c2528b3952fa9e615d5, since it
breaks resume from suspend-to-ram on Rafael's Acer Ferrari One.
NetworkManager thinks everything is ok, but it can't connect to the AP
to get an IP address after the resume.
In fact, it even breaks resume for non-ath9k chipsets: reverting it also
fixes Rafael's Toshiba Protege R500 with the iwlagn driver. As Johannes
says:
"Indeed, this patch needs to be reverted. That mac80211 change is wrong
and completely unnecessary."

I made a V2 of this patch on top of my patches for VFS switches.
All the changes were due to change in some offsets.
rename - change name of file or directory
size[4] Trename tag[2] fid[4] newdirfid[4] name[s]
size[4] Rrename tag[2]
The rename message is used to change the name of a file, possibly moving it
to a new directory. The 9P wstat message can only rename a file within the
same directory.

Use the same message, allocated during startup. No need to reallocate a
new one each time around (and potentially ENOMEM).

The auth_reply handler will (re)send any pending requests. For the
initial mon authenticate phase, that's correct, but when a auth ticket
renewal races with an in-flight request, we may resend a request message
that is already in flight. Avoid this by revoking the message before
sending it.
We should also avoid resending requests at all during ticket renewal; that
will come soon.

The C99 specification states in section 6.11.5:
The placement of a storage-class specifier other than at the beginning
of the declaration specifiers in a declaration is an obsolescent
feature.
