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:
v5.4.87 upstream stable release
from git://git.kernel.org/
net/sched: sch_taprio: reset child qdiscs before freeing them
md/raid10: initialize r10_bio->read_slot before use.

jffs2: Allow setting rp_size to zero during remounting
jffs2: Fix NULL pointer dereference in rp_size fs option parsing
scsi: block: Fix a race in the runtime power management code

tools headers UAPI: Sync linux/const.h with the kernel headers
null_blk: Fix zone size initialization
of: fix linker-section match-table corruption
cgroup: Fix memory leak when parsing multiple source parameters
scsi: cxgb4i: Fix TLS dependency
Bluetooth: hci_h5: close serdev device and free hu in h5_close
