The value bytes comes from the filesystem which is about to be
mounted. We cannot trust that the value is always in the range
we expect it to be.
Check its value before using it to calculate the length for the
crc32_le call. It value must be larger (or equal) sumoff + 4.

After a NOHZ idle sleep the wheel must be forwarded to current jiffies. There
might be expired timers so the current code loops and checks the epxired
buckets for timers. This can take quite some time for long NOHZ idle periods.

The wheel clock is stale when a cpu goes into a long idle sleep. This has the
side effect, that timers which are queued end up in the outer wheel
levels. That results in coarser granularity.
To solve this, we keep track of the idle state and forward the wheel clock
whenever it's possible.

Hi Andrew,
Please send the following patch to upstream (hopefully in this cycle).
It fixes a memory overrun issue due to incomplete sanity check of
on-disk super block size information, which can result in a kernel
panic, for instance, in the case where a non-nilfs volume is
accidentally mounted t
This was a failed attempt to optimize the timer expiry in idle, which was
disabled and never revisited. Remove the cruft.

The existing optimization for same expiry time in mod_timer() checks whether
the timer expiry time is the same as the new requested expiry time. In the old
timer wheel implementation this does not take the slack batching into account,
neither does the new implementation

SPI slave devices are not created when looking up driver for the slave

This allows binding spidev on any slave device by hand using sysfs
without adding superfluous compatibles or any other needless
complication.
Note that any slave driver that requires configuration will fail to
probe anyway. Only a driver that binds to anything can be bound
successfully.

Hello,
This small patchset makes it possible to bind spidev manually to any SPI slave
without much hassle.
Thanks

Michal Suchanek (3):
spi: spidev: fix the check for spidev in dt
spi: of: allow instantiating slaves without a driver
drivers core: allow id match override when manuall
The check is supposed to warn about spidev specified directly in
devicetree as compatible. This just does not work. I have a devicetree
with no compatible whatsoever and hacked my kernel so I can manually
bind spidev. This still triggers.
Also I have no idea how this could have build with ! CONFIG
