architectures by read Kconfig.debug.Commit 85d3a316c71 ("kmemleak: use rbtree instead of prio tree")

Concurrent access to alloc_blocks in hfsplus_inode_info() is protected
by extents_lock mutex. This patch fixes two instances where
alloc_blocks modification was not protected with this lock.This fixes possible allocation bitmap corruption in race conditions
while extending and truncating files.[akpm@linux-foundation.org: take extents_lock before taking a copy of ->alloc_blocks]

Add code to check sizes of on-disk data of metadata files such as inode
size, segment usage size, DAT entry size, and checkpoint size. Although
these sizes are read from disk, the current implementation doesn't check
them.If these sizes are not sane on disk, it can cause out-of-range access to
metadata or memory access overrun on metadata block buffers due to
overflow in sundry calculations.Both lower limit and upper limit of metadata sizes are verified to
prevent these issues.Signed-off-by: Ryusuke Konishi

With this ioctl the segment usage entries in the SUFILE can be updated
from userspace.This is useful, because it allows the userspace GC to modify and update
segment usage entries for specific segments, which enables it to avoid
unnecessary write operations.If a segment needs to be cleaned, but there is no or very little
reclaimable space in it, the cleaning operation basically degrades to a
useless moving operation. In the end the only thing that changes is the
location of the data and a timestamp in the segment usage information.
With this ioctl the GC can skip the cleaning and update the segment
usage entries directly instead.This is basically a shortcut to cleaning the segment. It is still
necessary to read the segment summary information, but the writing of
the live blocks can be skipped if it's not worth it.[konishi.ryusuke@lab.ntt.co.jp: add description of NILFS_IOCTL_SET_SUINFO ioctl]

The patch "rtc: verify a critical argument to rtc_update_irq() before
using it" introduces validation for rtc_device in the RTC core, so there
are no need to check this argument for rtc_update_irq() from the
drivers.This patch removes such check for the existing rtc_update_irq() users.

NO_IRQ may be defined as '(unsigned int) -1' in some architectures (arm,
sh ...), and either may not be defined in some architectures (arm64) which
can enable RTC_DRV_S3C.Also since platform_get_irq returns err-code in case of any error, we do
not need to intialize s3c_rtc_alarmno and s3c_rtc_tickno.Signed-off-by: Pankaj Dubey

Using platform_get_irq_byname() to retrieve the IRQ number returns the
VIRQ number rather than the local IRQ number for the device. Passing that
value then into regmap_irq_get_virq() causes a failure because the
function is expecting the local IRQ number (e.g. 0, 1, 2, 3, etc).This patch removes use of regmap_irq_get_virq() to prevent this failure
from happeningSigned-off-by: Adam Thomson
