If the swapped-out memory is large, such as tens of gigabytes, we will
allocate a large management structure, which may be tens of megabytes or
hundreds of megabytes. So if we use kmalloc to allocate management
structures it may fail.
Fix this by changing kmalloc to kvzalloc and kfree to kvfree.

--------------------------------

[ Upstream commit 47c29d69 ]

In bq24190_probe, &bdi->input_current_limit_work is bound
with bq24190_input_current_limit_work. When external power
changed, it will call bq24190_charger_external_power_changed
 to start the work.

If we remove the module which will call bq24190_remove to make
cleanup, there may be a unfinished work. The possible
sequence is as follows:

CPU0                  CPUc1

                    |bq24190_input_current_limit_work
bq24190_remove      |
power_supply_unregister  |
device_unregister   |
power_supply_dev_release|
kfree(psy)          |
                    |
                    | power_supply_get_property_from_supplier
                    |   //use

Fix it by finishing the work before cleanup in the bq24190_remove

The problem of service interruption and loss may be triggered during
live migration. In order to ensure normal business, it is necessary to
resend an interrupt in the live migration driver.

And in the QM service driver, it is guaranteed that the retransmission
interrupt can be received normally.

The driver needs to migrate the perf context if the current using CPU going

cpu_online_mask() hasn't updated yet and still includes the CPU going to

commit 07db5e24 upstream.

The current hfsplus_put_super first calls hfs_btree_close on
sbi->ext_tree, then invokes iput on sbi->hidden_dir, resulting in an
use-after-free issue in hfsplus_release_folio.

As shown in hfsplus_fill_super, the error handling code also calls iput
before hfs_btree_close.

To fix this error, we move all iput calls before hfsplus_btree_close.

Note that this patch is tested on Syzbot.

prevents the bridge from forwarding CPU MMIO requests in the downstream
direction, and these MMIO accesses to devices below the bridge happen even
after .shutdown(), e.g., to print console messages.  LS7A neither forwards
the requests nor sends an unsuccessful completion to the CPU, so the CPU
waits forever, resulting in the hang.

As hns_roce_init_hem_table() is always called with use_lowmem
being '1', and table->lowmem is set according to that argument,
so remove table->lowmem too.

Also, as the table->lowmem is used to indicate a dma buffer
is allocated with GFP_HIGHUSER or GFP_KERNEL, and calling
dma_alloc_coherent() with GFP_KERNEL seems like a common
pattern.

!799 SCSI: SSSRAID: fix the issue that consider the scenario of HDD will occur unexpected high latency when pressure, concurrent, time all big enough

Merge Pull Request from: @steven-song3 
 
[issue description]
HDD will occur unexpected high latency when pressure, concurrent, time all big enough.
[steps to reproduce the problem]
1. 16 HDDs create 16 bare disks, each disk starts a thread, each thread
   is bound to a core, and the queue depth is 64
2. Issue read & write mixed I/O to the drive letters corresponding to
   rawdrive
3. After the long read and write IO period is completed, observe the
   maximum delay in the printout of the fio tool
[Probability of occurrence]
100%
[Expected results]
The maximum delay in the printout of the FIO tool does not exceed 10 seconds
[Root cause]
Muti-queue implementation will cause high concurrent in each different hardware
dispatch queue is not suitable for HDD.
[Solution]
Introduce work_mode module parameter to fastened total I/O queue number
equal to 1 and maximum concurrent I/O is 4k (according to RAID cured performance)

bugzilla: https://gitee.com/openeuler/kernel/issues/I6K5OH
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=f773f0a331d6c41733b17bebbc1b6cae12e016f5

--------------------------------

During the processing of the bgt, if the sync_erase() return -EBUSY
or some other error code in __erase_worker(),schedule_erase() called
again lead to the down_read(ubi->work_sem) hold twice and may get
block by down_write(ubi->work_sem) in ubi_update_fastmap(),
which cause deadlock.

          ubi bgt                        other task
 do_work
  down_read(&ubi->work_sem)          ubi_update_fastmap
  erase_worker                         # Blocked by down_read
   __erase_worker                      down_write(&ubi->work_sem)
    schedule_erase
     schedule_ubi_work
      down_read(&ubi->work_sem)

Fix this by changing input parameter @nested of the schedule_erase() to
'true' to avoid recursively acquiring the down_read(&ubi->work_sem).

Also, fix the incorrect comment about @nested parameter of the
schedule_erase() because when down_write(ubi->work_sem) is held,
the @nested is also need be true.
