When we fail in ->write_begin()/->direct_IO(), our allocated node block in disk
and page cache are still kept, despite these may not be used again.
This patch introduce f2fs_write_failed() to handle the error case of these two
interfaces, it will truncate page cache and blocks of this file
We assume that modification of some special application could result in zeroed
name_len, or it is consciously made by somebody. We will deadloop in
find_in_block when name_len of dir entry is zero.
This patch is added for preventing deadloop in above scenario.

The JIT compiler emits A64 instructions. It supports eBPF only.
Legacy BPF is supported thanks to conversion by BPF core.
JIT is enabled in the same way as for other architectures:

Or for additional compiler output:

Most of the infrastructure is in place now, with only little left. How to find
siblings ?
Stephen Boyd suggested to compare "clocks" properties from CPU's DT node and
siblings should match. This patch adds another routine find_siblings() which
calls of_property_match() to find if CPUs share clock
OPPs can be populated statically, via DT, or added at run time with
dev_pm_opp_add().
While this driver handles the first case correctly, it would fail to populate
OPPs added at runtime. Because call to of_init_opp_table() would fail as there
are no OPPs in DT and probe will return early.
To fix
Commit 8d6f7c5a: "powerpc/powernv: Make it possible to skip the IRQHAPPENED
check in power7_nap()" added code that prevents cpus from checking for
pending interrupts just before entering sleep state, which is wrong. These
interrupts are delivered during the soft irq disabled state of the cpu.

Appreciate your help to sort out the power supply maintainer issue. The
subsystem is not active after February 2014. No response from maintainer and
the
last commit on git://git.infradead.org/battery-2.6 was on 2014-02-01. Appreciate

The RFC patch below adds a new flag for dup3().
(For simplicity, I'm just reusing O_EXCL for now.)
I am assuming calling f_op->flush() twice instead of just once
before closing the file is not harmful.
The idea is to extend dup3() so that we can catch close() errors

The EHCI packet buffer in/out threshold is programmable for Intel Quark X1000

can be programmed to 0x80 dwords (512 Bytes) to maximize the perfomrance,
but only when isochronous/interrupt

Now, swap_info_get hides lock holding by doing it internally
but releasing the lock so caller should release the lock.
Normally, it's not a good pattern and I need to handle lock
from caller in next patchset.

Normally, I/O completed pages for reclaim would be rotated into
inactive LRU tail without freeing. The why it works is we can't free
page from atomic context(ie, end_page_writeback) due to vaious locks
isn't aware of atomic context.
So for reclaiming the I/O completed pages, we need one more
Invalidate dirty/writeback page and file/swap I/O for reclaiming
are asynchronous so that when page writeback is completed,
it will be rotated back into LRU tail for freeing in next reclaim.
But it would make unnecessary CPU overhead and more aging
with higher priority of reclaim than necessary
For release page from atomic context(ie, softirq), locks
related to the work should be aware of that.
There are two locks.
One is mapping->tree_lock and the other is swap_info_struct->lock.
The mapping->tree_lock is alreay aware of irq so it's no problem
but swap_info_struct->lock isn't so

Hey Tony and Russel ,
There is a FIX ME message in this function of the file stated in my
subject line.
I was wondering what locking is needed here due to not having experience with
omap subsystem(s).

Hi Hugh,
I've been observing a very nonspecific hang involving some mutexes from fs/ but
without any lockdep output or a concrete way to track it down.
It seems that today was my lucky day, and after enough tinkering I've managed
to get output out of lockdep, which pointed me to shmem:
