Hello,
Currently kswapd queues dirty pages for writeback if scanning at an elevated

of unqueued dirty encountered. Since commit mm: vmscan: Flatten kswapd

zone

Currently kswapd checks if it should start writepage as it shrinks
each zone without taking into consideration if the zone is balanced or
not. This is not wrong as such but it does not make much sense either.
This patch checks once per pgdat scan if kswapd should be writing pages.
Signed-off-by:
Historically, kswapd used to congestion_wait() at higher priorities if it
was not making forward progress. This made no sense as the failure to make
progress could be completely independent of IO. It was later replaced by
wait_iff_congested() and removed entirely by commit 258401a6 (mm: don't
wait
In the past, kswapd makes a decision on whether to compact memory after the
pgdat was considered balanced. This more or less worked but it is late to
make such a decision and does not fit well now that kswapd makes a decision
whether to exit the zone scanning loop depending on reclaim progress.
Page reclaim at priority 0 will scan the entire LRU as priority 0 is
considered to be a near OOM condition. Kswapd can reach priority 0 quite
easily if it is encountering a large number of pages it cannot reclaim
such as pages under writeback. When this happens, kswapd reclaims very
aggressively
This series does not fix all the current known problems with reclaim but
it addresses one important swapping bug when there is background IO.
Changelog since V3
o Drop the slab shrink changes in light of Glaubers series and
discussions highlighted that there were a number of potential
kswapd stops raising the scanning priority when at least SWAP_CLUSTER_MAX
pages have been reclaimed or the pgdat is considered balanced. It then
rechecks if it needs to restart at DEF_PRIORITY and whether high-order
reclaim needs to be reset. This is not wrong per-se but it is confusing
to follow
Simplistically, the anon and file LRU lists are scanned proportionally
depending on the value of vm.swappiness although there are other factors
taken into account by get_scan_count(). The patch mm: vmscan: Limit
the number of pages kswapd reclaims limits the number of pages kswapd
reclaims but it
The number of pages kswapd can reclaim is bound by the number of pages it
scans which is related to the size of the zone and the scanning priority. In
many cases the priority remains low because it's reset every SWAP_CLUSTER_MAX
reclaimed pages but in the event kswapd scans a large number of pages
BTW...

The --percent-limit option is for not showing small overheaded entries
in the output. Maybe we want to set a certain default value like 0.1.

This series is against tip's x86/apic branch.
Allow conserving interrupt resources when PCI devices in multiple-MSI
mode send a number of MSIs which is not a power-of-two. This update
will prevent wasting of any resources associated with unused MSIs in
general (i.e. IRQ descriptors) and x86
When multiple MSIs are enabled with pci_enable_msi_block(), the
requested number of interrupts 'nvec' is rounded up to the nearest
power-of-two value. The result is then used for setting up the
number of MSI messages in the PCI device and allocation of
interrupt resources in the operating system
Current multiple-MSI implementation does not take into account
actual number of requested MSIs and always rounds that number
to a closest power-of-two value. Yet, a number of MSIs a PCI
device could send (and therefore a number of messages a device
driver could request) may be a lesser

Yes, the above and hash_page() are two C functions for a same exception.
And the exception hooks enable RCU usage in those C codes. But for asm
codes, I think we could assume that there would be no RCU usage there,
so we don't need wrap them

Because I used alloc_cpumask_var instead of zalloc_cpumask_var :(
Fix is queued and will hit linus tree
