How can I schedule driver's worker and threaded IRQ on the same core?
For work queue we have schedule_delayed_work_on () API available.
But how to schedule the threaded IRQ on the same core where my

All code paths seems covered. Now we can map huge zero page on read page
fault.

During testing I noticed big (up to 2.5 times) memory consumption overhead
on some workloads (e.g. ft.A from NPB) if THP is enabled.
The main reason for that big difference is lacking zero page in THP case.
We have to allocate a real page

We can't split huge zero page itself, but we can split the pmd which
points to it.
On splitting the pmd we create a table with all ptes set to normal zero
page.

Pass vma instead of mm and add address parameter.
In most cases we already have vma on the stack. We provides
split_huge_page_pmd_mm() for few cases when we have mm, but not vma.
This change is preparation to huge zero pmd splitting

We want to get page fault on write attempt to huge zero page, so let's
keep it write-protected.

Instead of allocating huge zero page on hugepage_init() we can postpone it
until first huge zero page map. It saves memory if THP is not in use.
cmpxchg() is used to avoid race on huge_zero_pfn initialization.

For now let's allocate the page on hugepage_init(). We'll switch to lazy
allocation later.
We are not going to map the huge zero page until we can handle it
properly on all code paths.

Hi,
This patchset improves bash completion support for perf tools. Some
option names are really painful to type so here comes a support for
completing those long option names. But I still think the
--showcpuutilization option needs to be renamed (at least adding a
couple of dashes in it).
The '_get_comp_words_by_ref' function is available from the bash
completion v1.2 so that earlier version emits following warning:
$ perf reTAB_get_comp_words_by_ref: command not found
Use older '_get_cword' method when the above function doesn't exist.
Cc: Frederic Weisbecker
Add internal --list-opts option to print all of long option names to
stdout so that it can be used for bash completion engine.

Support the LUN parameter change event. Currently, the host fires this event
when the capacity of a disk is changed from the virtual machine monitor.
The resize then appears in the kernel log like this:
sd 0:0:0:0: [sda] 46137344 512-byte logical blocks: (23.6 GB/22.0 GIb)
sda: detected
virtio-scsi needs to report LUNs greater than 256 using the flat
format. Because the Linux SCSI layer just maps the SCSI LUN to
an u32, without any parsing, these end up in the range from 16640
to 32767. Fix max_lun to account for the possibility that logical
unit numbers are encoded with the
