Public bug reported:
SRU Justification
Impact:
The upstream process for stable tree updates is quite similar
in scope to the Ubuntu SRU process, e.g., each patch has to
demonstrably fix a bug, and each patch is vetted by upstream
by originating either directly from a mainline/stable Linux tree or
a minimally backported form of that patch. The following upstream
stable patches should be included in the Ubuntu kernel:
v5.10.5 upstream stable release
from git://git.kernel.org/
Linux 5.10.5
device-dax: Fix range release
ext4: avoid s_mb_prefetch to be zero in individual scenarios
dm verity: skip verity work if I/O error when system is shutting down
ALSA: pcm: Clear the full allocated memory at hw_params
io_uring: remove racy overflow list fast checks
s390: always clear kernel stack backchain before calling functions
tick/sched: Remove bogus boot "safety" check
drm/amd/display: updated wm table for Renoir
ceph: fix inode refcount leak when ceph_fill_inode on non-I_NEW inode fails

i3c master: fix missing destroy_workqueue() on error in i3c_master_register
powerpc: sysdev: add missing iounmap() on error in mpic_msgr_probe()
rtc: pl031: fix resource leak in pl031_probe
quota: Don't overflow quota file offsets
module: set MODULE_STATE_GOING state when a module fails to load
rtc: sun6i: Fix memleak in sun6i_rtc_clk_init
io_uring: check kthread stopped flag when sq thread is unparked
fcntl: Fix potential deadlock in send_sig{io, urg}()
ext4: check for invalid block size early when mounting a file system
bfs: don't use WARNING: string when it's just info.
ALSA: rawmidi: Access runtime->avail always in spinlock
ALSA: seq: Use bool for snd_seq_queue internal flags

media: gp8psk: initialize stats at power control logic
misc: vmw_vmci: fix kernel info-leak by initializing dbells in
vmci_ctx_get_chkpt_doorbells()
reiserfs: add check for an invalid ih_entry_count
fbcon: Disable accelerated scrolling
Bluetooth: hci_h5: close serdev device and free hu in h5_close

io_uring: use bottom half safe lock for fixed file data
io_uring: don't assume mm is constant across submits
lib/zlib: fix inflating zlib streams on s390
mm: memmap defer init doesn't work as expected
mm/hugetlb: fix deadlock in hugetlb_cow error path
scsi: block: Fix a race in the runtime power management code
opp: Call the missing clk_put() on error
opp: fix memory leak in _allocate_opp_table
spi: dw-bt1: Fix undefined devm_mux_control_get symbol
jffs2: Fix NULL pointer dereference in rp_size fs option parsing
jffs2: Allow setting rp_size to zero during remounting
io_uring: close a small race gap for files cancel
drm/amd/display: Add get_dig_frontend implementation for DCEx
md/raid10: initialize r10_bio->read_slot before use.
