This patch introduces the improvement fast symlinks to allow storage of
the target path within inode, thus symlinks with short target paths are
more accessed quickly. It will fall back to using the original slow
symlink if the target path exceeds the available inode space.

Current apply_workqueue_attrs() includes pwqs-allocation and pwqs-installation,

So here is another round of this series, which is the result of
earlier discussions with Linus and his suggestions around
improvements to clocksource validation in the hope we can more
easily catch bad hardware.
There's also a few cleanups Linus suggested as well as a few I've been
meaning to get
When calculating the current delta since the last tick, we
currently have no hard protections to prevent a multiplication
overflow from occurring.
This patch introduces infrastructure to allow a cap that
limits the read delta value to the max_cycles value, which is
where an overflow would occur.
It was suggested that the underflow/overflow protection
should probably throw some sort of warning out, rather
then just silently fixing the issue.
So this patch adds some warnings here. The flag variables
used are not protected by locks, but since we can't print
from the reading functions, just b
The previous clocks_calc_max_nsecs had some unecessarily
complex bit logic to find the max interval that could cause
multiplication overflows. Since this is not in the hot

While cleaning up some clocksource code, I noticed the
time_32 implementation uses the clocksource_hz2mult()
helper, but doesn't use the clocksource_register_hz()
method.
I don't believe the Sparc clocksource is a default

the mult/shift pair.
So co
The clocksource watchdog reporting has been less helpful

The clocksource logic has a number of places where we try to

A long running project has been to cleanup remaining uses

Commit e5863d9ad ("dm: allocate requests in target when stacking on

in request-based DM -- it enabled stacking a old-style (request_fn)
request_queue ontop of the underlying blk-mq device(s). This first step
didn't improve per
This patchset updates request-based DM (used exclussively by DM
multipath) to support blk-mq I/O path or the old ->request_fn I/O
path -- the default is still the old ->request_fn I/O path.
Like was done for SCSI, I've exposed a dm-mod.ko 'use_blk_mq' module
parameter and a CONFIG_DM_MQ_DEFAULT.
dm_mq_queue_rq() is in atomic context so care must be taken to not
sleep -- as such GFP_ATOMIC is used for the md->bs bioset allocations
and dm-mpath's call to blk_get_request(). In the future the bioset
allocations will hopefully go away (by removing support for partial
completions of a request).
Rename blk_mq_run_queues to blk_mq_run_hw_queues, add async argument,
and export it.
DM's suspend support must be able to run the queue without starting
stopped hw queues.

This adds a missing break statement to VFIO_DEVICE_SET_IRQS handler
without which vfio_pci_set_err_trigger() would never be called.
While we are here, add another "break" to VFIO_PCI_REQ_IRQ_INDEX case
so if we add more indexes later, we won't miss it.

Use %pS for actual addresses, otherwise you'll get bad output
on arches like ppc64 where %pF expects a function descriptor.

Hi,
I am working on the JIT support to improve the flow and have
perf record inject the MMAPs at the end of the collection. For
that I piggyback on the buildid pass. To avoid rewriting the entire perf.data
file, I simply append the the MMAP records at the end of the file. And that
puts them out-of

other architectures, refrain from setting a bad example that people
