If the read-only flag is true on a SCSI disk, re-reading the partition
table sets the flag back to false.
To observe this bug, you can run:
1. blockdev --setro /dev/sda
2. blockdev --rereadpt /dev/sda
3. blockdev --getro /dev/sda
This commit reads the disk's old state and combines it with the de
That's why page_alloc_init_late() needs spin_lock_irq(). If a CPU is
holding deferred_zone_grow_lock with enabled interrupts and an
interrupt comes in on that CPU and the CPU runs deferred_grow_zone() in
its interrupt handler, we deadlock.
lockdep knows about this bug and should have reported it

According to the i.MX25 reference manuals, each SSI has four FIFOs. All
of those FIFOs can store up to 15 entries.
The fsl_ssi driver's internal default for the FIFO depth in 8. Set our
non-default FIFO depth explicitly in the Device Tree.

The ssi1_ipg clock depends on ssi1_ipg_per. Set ssi1_ipg_per as parent
clock of ssi1_ipg. Without this link, the fsl_ssi driver does not
activate the ssi1_ipg clock correctly and ssi1 is unable to transfer
audio data.
Fix the parent clock of ssi2 as well, it shows the same behaviour.

get a prefix. Instead, move to a subdirectory for cleaner handling.

Hi Greg,
Please take these two patches for LKDTM. The first is a mass renaming to
move under a new "lkdtm" subdirectory in drivers/misc. The second just
adds a missed SPDX line to one of the LKDTM source files.

This change avoid needlessly searching for more timers in

Device drivers use get_device_system_crosststamp() to produce precise
system/device cross-timestamps. The PHC clock and ALSA interfaces,
for example, make the cross-timestamps available to user applications.
On Intel platforms, get_device_system_crosststamp() requires a TSC
value derived from ART (

Fix the objtool build when cross-compiling a 64-bit kernel on a 32-bit
host. This also simplifies read_retpoline_hints() a bit and makes its
implementation similar to most of the other annotation reading
functions.

This patchset fixes errors and checks found by checkpatch.pl in the
staging/iio/meter. These series fixes:
* Removes the use of 4 digit octal by replaces IIO_DEV_ATTR_CH_OFF by
IIO_DEVICE_ATTR;
* Removes unnecessary macro;
* Aligns open parenthesis;
Changes v2:
- Aligns one extra open par
This patch fixes the checkpatch.pl checks:
staging/iio/meter/ade7854-spi.c:19: CHECK: Alignment should match open
parenthesis
staging/iio/meter/ade7854-spi.c:44: CHECK: Alignment should match open

The macro IIO_DEV_ATTR_CH_OFF is a wrapper for IIO_DEVICE_ATTR, with a
tiny change in the name definition. This extra macro does not improve
the readability and also creates some checkpatch errors.
This patch fixes the checkpatch.pl errors:
staging/iio/meter/ade7753.c:391: ERROR: Use 4 digit octa
This patch removes the macro IIO_DEV_ATTR_CH_OFF. The macro
IIO_DEV_ATTR_CH_OFF is not required, due to the replace of it by the
direct use of IIO_DEVICE_ATTR in files staging/iio/meter/ade7759.c and
staging/iio/meter/ade7753.c.

To allow for easier build test coverage and run-time testing, this allows
multiple compression algorithms to be built into pstore. Still only one

There is no need for the calls to BUG_ON() in this driver, which are
used to check if mbo or mbo->context are NULL; mbo is never NULL, and
if mbo->context is NULL it would have already been dereferenced and
oopsed before reaching the BUG_ON().
