ll_new_hw_segment() is reached only in case of single range discard
merge, and we don't have max discard segment size limit actually, so
it is wrong to run the following check:
if (req->nr_phys_segments + nr_phys_segs > blk_rq_get_max_segments(req))
it may be always false since req->nr_phys_segments is initialized as
one, and bio's segment count is still 1, blk_rq_get_max_segments(reg)
is 1 too.
Fix the issue by not doing the check and bypassing the calculation of
discard request's nr_phys_segments.

Syzbot reported memory leak in xfrm_user_rcv_msg(). The
problem was is non-freed skb's frag_list.
In skb_release_all() skb_release_data() will be called only
in case of skb->head != NULL, but netlink_skb_destructor()
sets head to NULL. So, allocated frag_list skb should be
freed manualy, since consume_skb() won't take care of it

Split __gfs2_unstuff_inode off from gfs2_unstuff_dinode and clean up the

In gfs2_page_mkwrite, unstuff inodes before locking the page. That

We're setting an error number so that block_page_mkwrite_return

The cause of the problem is as follows:
1. when cat /sys/devices/system/memory/memory0/valid_zones,
test_pages_in_a_zone() will be called.
2. test_pages_in_a_zone() finds the zone according to stat_pfn = 0.
The smallest pfn of the numa node in the mips architecture is 128,
and the page corresponding to the previous 0~127 pfn is not
initialized (page->flags is 0xFFFFFFFF)
3. The nid and zonenum obtained using page_zone(pfn_to_page(0)) are out
of bounds in the corresponding array,
&NODE_DATA(page_to_nid(page))->node_zones[page_zonenum(page)],
access to the out-of-bounds zone member variables appear abnormal,
resulting in Oops.
Therefore, it is necessary to keep the page between 0 and the minimum
pfn to prevent Oops from appearing.

Currently firmware passes CCF specific flags to ZynqMP clock driver.
So firmware needs to be updated if CCF flags are changed. The firmware
should have its own 'flag number space' that is distinct from the
common clk framework's 'flag number space'. So define and use ZynqMP
specific common clock flags instead of using CCF flags.

Pull btrfs updates from David Sterba:
"A normal mix of improvements, core changes and features that user have
been missing or complaining about.
User visible changes:
- new sysfs exports:
- add sysfs knob to limit scrub IO bandwidth per device
- device stats are also available in
/sys/fs/btrfs/FSID/devinfo/DEVID/error_stats
- support cancellable resize and device delete ioctls
- change how the empty value is interpreted when setting a property,
so far we have only 'btrfs.compression' and we need to distinguish
a reset to defaults and setting "do not compress", in general the
empty value will always mean 'reset to defaults' for any other
property, for compression it's either 'no' or 'none' to forbid
compression
Performance improvements:
- no need for full sync when truncation does not touch extents,
reported run time change is -12%
- avoid unnecessary logging of xattrs during fast fsyncs (+17%
throughput, -17% runtime on xattr stress workload)
Core:
- preemptive flushing improvements and fixes
- adjust clamping logic on multi-threaded workloads to avoid
flushing too soon
- take into account global block reserve, may help on almost full
filesystems
- continue flushing when there are enough pending delalloc and
ordered bytes
- simplify logic around conditional transaction commit, a workaround
used in the past for throttling that's been superseded by ticket
reservations that manage the throttling in a better way
- subpage blocksize preparation:
- submit read time repair only for each corrupted sector
- scrub repair now works with sectors and not pages
- free space cache (v1) works with sectors and not pages
- more fine grained bio tracking for extents
- subpage support in page callbacks, extent callbacks, end io
callbacks
- simplify transaction abort logic and always abort and don't check
various potentially unreliable stats tracked by the transaction
- exclusive operations can do more checks when started and allow eg.
cancellation of the same running operation
- ensure relocation never runs while we have send operations running,
e.g. when zoned background auto reclaim starts
Fixes:
- zoned: more sanity checks of write pointer
- improve error handling in delayed inodes
- send:
- fix invalid path for unlink operations after parent
orphanization
- fix crash when memory allocations trigger reclaim
- skip compression of we have only one page (can't make things
better)
- empty value of a property newly means reset to default
Other:
- lots of cleanups, comment updates, yearly typo fixing
- disable build on platforms having page size 256K"

Platform STM32MP1 can be used in configuration where some clock
resources cannot be accessed by Linux kernel when executing in non-secure
state of the CPU(s).
In such configuration, the RCC clock driver must not register clocks
it cannot access.
They are expected to be registered from another clock driver such
as the SCMI clock driver.
This change uses specific compatible string "st,stm32mp1-rcc-secure"
to specify RCC clock driver configuration where RCC is secure.

Tanner Love says:
====================
net: update netdev_rx_csum_fault() print dump only once
First patch implements DO_ONCE_LITE to abstract uses of the ".data.once"
trick. It is defined in its own, new header file -- rather than
alongside the existing DO_ONCE in include/linux/once.h -- because
include/linux/once.h includes include/linux/jump_label.h, and this
causes the build to break for some architectures if
include/linux/once.h is included in include/linux/printk.h or
include/asm-generic/bug.h.
Second patch uses DO_ONCE_LITE in netdev_rx_csum_fault to print dump
only once.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Printing this stack dump multiple times does not provide additional
useful information, and consumes time in the data path. Printing once
is sufficient.

Certain uses of "do once" functionality reside outside of fast path,
and so do not require jump label patching via static keys, making
existing DO_ONCE undesirable in such cases.
Replace uses of __section(".data.once") with DO_ONCE_LITE(_IF)?
This patch changes the return values of xfs_printk_once, printk_once,
and printk_deferred_once. Before, they returned whether the print was
performed, but now, they always return true. This is okay because the
return values of the following macros are entirely ignored throughout
the kernel:
- xfs_printk_once
- xfs_warn_once
- xfs_notice_once
- xfs_info_once
- printk_once
- pr_emerg_once
- pr_alert_once
- pr_crit_once
- pr_err_once
- pr_warn_once
- pr_notice_once
- pr_info_once
- pr_devel_once
- pr_debug_once
- printk_deferred_once
- orc_warn
Changes
v3:
- Expand commit message to explain why changing return values of
xfs_printk_once, printk_once, printk_deferred_once is benign

1 warning generated.
mac_addr is only used to store the value retrieved from
of_get_mac_address(), which is then copied into the base_mac member of
the sparx5 struct using ether_addr_copy(). It is easier to just use the
base_mac address directly, which avoids the warning and the extra copy.

The SJA1105P/Q/R/S and SJA1110 may have the same layout for the command
to read/write/search for L2 Address Lookup entries, but as explained in
the comments at the beginning of the sja1105_dynamic_config.c file, the
command portion of the buffer is at the end, and we need to obtain a
pointer to it by adding the length of the entry to the buffer.
Alas, the length of an L2 Address Lookup entry is larger in SJA1110 than
it is for SJA1105P/Q/R/S, so we need to create a common helper to access
the command buffer, and this receives as argument the length of the
entry buffer.
