Page cache radix tree slots are usually stabilized by the page lock,
but shmem's swap cookies have no such thing. Because the overall
truncation loop is lockless, the swap entry is currently confirmed by
a tree lookup and then deleted by another tree lookup under the same
tree lock region.

This code used to have its own lru cache pagevec up until a0b8cab3
("mm: remove lru parameter from __pagevec_lru_add and remove parts of
pagevec API"). Now it's just add_to_page_cache() followed by
lru_cache_add(), might as well use add_to_page_cache_lru() directly.

Reclaim will be leaving shadow entries in the page cache radix tree
upon evicting the real page. As those pages are found from the LRU,
an iput() can lead to the inode being freed concurrently. At this
point, reclaim must no longer install shadow pages because the inode
freeing code needs to
Previously, page cache radix tree nodes were freed after reclaim
emptied out their page pointers. But now reclaim stores shadow
entries in their place, which are only reclaimed when the inodes
themselves are reclaimed. This is problematic for bigger files that
are still in use after they have a
Fengguang Wu's build testing spotted problems with inc_zone_state()
and dec_zone_state() on UP configurations in out-of-tree patches.
inc_zone_state() is declared but not defined, dec_zone_state() is
missing entirely.
Just like with *_zone_page_state(), they can be defined like their
The VM maintains cached filesystem pages on two types of lists. One
list holds the pages recently faulted into the cache, the other list
holds pages that have been referenced repeatedly on that first list.
The idea is to prefer reclaiming young pages over those that have
shown to benefit from
The radix tree hole searching code is only used for page cache, for
example the readahead code trying to get a a picture of the area
surrounding a fault.
It sufficed to rely on the radix tree definition of holes, which is
"empty tree slot". But this is about to change, though, as shadow

shmem mappings already contain exceptional entries where swap slot
information is remembered.
To be able to store eviction information for regular page cache,
prepare every site dealing with the radix trees directly to handle
entries other than pages.
The common lookup functions will filter out
Provide a function that does not just delete an entry at a given
index, but also allows passing in an expected item. Delete only if
that item is still located at the specified index.
This is handy when lockless tree traversals want to delete entries as
well because they don't have to do an

Hi all,
Today's linux-next merge of the parisc-hd tree got a conflict in
arch/parisc/include/asm/elf.h between commit 9dabf60dc4ab ("parisc: add
flexible mmap memory layout support") from Linus' tree and commit
13de8ec38997 ("parisc: add flexible mmap memory layout support") from the
parisc-hd

Add a driver for the hardware watchdogs in NVIDIA Tegra SoCs (tegra30 and
later). This driver will configure one watchdog timer that will reset the
system in the case of a watchdog timeout.
This driver binds to the nvidia,tegra30-timer device node and gets its
register base from there.
Added timers that are present in tegra30 and later, that are NOT in tegra20.
Also, some of these timer bases are needed in the tegra watchdog driver, so
separate them out into a header file that both the clocksource driver and
the watchdog driver can share them.

There are some differences between tegra20's timer registers and tegra30's
(and later). For example, tegra30 has more timers. In addition, watchdogs
are not present in tegra20.
Add this compatibility string in order to be able to distinguish
whether the additional timers and watchdogs are there
This patch series ultimately adds watchdog support for tegra30 and later
chips.
The existing tegra clocksource driver (drivers/clocksource/tegra20_timer.c)
sadly does not distinguish between tegra20 and tegra30 (and later), which
it should have done since the contents of the timer register base

Hmm, I think it might be because compound_head() == NULL here. Holger,
this looks like a race condition when allocating a compound page, did you
only see it once
