The reason is that:
since commit 0827e645fd35
("f2fs crypto: shrink size of the f2fs_crypto_ctx structure") is merged,
some fields in f2fs_crypto_ctx structure are merged into a union as they
will never be used simultaneously in write path, read path or on free list.
In f2fs_exit_crypto, we traverse each crypto ctx from free list, in this
moment, our free_list field in union is valid, but still we will try to
release memory space which is pointed by other invalid field in union
structure for each ctx.
Then the error occurs, let's fix it with this patch.

The driver allocates one page for each buffer on the rx ring, which is
too much on architectures like ppc64 and can cause unexpected allocation
failures when the system is under stress. Now, we keep a memory pool
per queue, and if the architecture's PAGE_SIZE is greater than 4k, we
fragment pages and assign each 4k segment to a ring element, which
reduces the overall memory consumption on such architectures. This
helps avoiding errors like the example below:

Rather than having a long sprawling __v7_setup function, which is hard
to maintain properly, move the CPU errata out of line.
While doing this, it was discovered that the Cortex-A15 errata had been
incorrectly added:
ldr r10, =0x00000c08 @ Cortex-A8 primary part number
teq r0, r10
bne 2f
/* Cortex-A8 errata */
b 3f
2: ldr r10, =0x00000c09 @ Cortex-A9 primary part number
teq r0, r10
bne 3f
/* Cortex-A9 errata */
3: ldr r10, =0x00000c0f @ Cortex-A15 primary part number
teq r0, r10
bne 4f
/* Cortex-A15 errata */
4:
This results in the Cortex-A15 test always being executed after the
Cortex-A8 and Cortex-A9 errata, which is obviously not what is intended.
The 'b 3f' labels should have been updated to 'b 4f'. The new structure
of:
/* Cortex-A8 Errata */
ldr r10, =0x00000c08 @ Cortex-A8 primary part number
teq r0, r10
beq __ca8_errata
/* Cortex-A9 Errata */
ldr r10, =0x00000c09 @ Cortex-A9 primary part number
teq r0, r10
beq __ca9_errata
/* Cortex-A15 Errata */
ldr r10, =0x00000c0f @ Cortex-A15 primary part number
teq r0, r10
beq __ca15_errata

Re-implement the physical address space switching to be architecturally
compliant. This involves flushing the caches, disabling the MMU, and
only then updating the page tables. Once that is complete, the system
can be brought back up again.
Since we disable the MMU, we need to do the update in assembly code.
Luckily, the entries which need updating are fairly trivial, and are
all setup by the early assembly code. We can merely adjust each entry
by the delta required.
Not only does this fix the code to be architecturally compliant, but it
fixes a couple of bugs too:
1. The original code would only ever update the first L2 entry covering
a fraction of the kernel; the remainder were left untouched.
2. The L2 entries covering the DTB blob were likewise untouched.
This solution fixes up all entries.

When we come to tear things down in netback_remove() and generate the
uevent it is possible that the xenstore directory has already been
removed (details below).
In such cases netback_uevent() won't be able to read the hotplug
script and will write a xenstore error node.
A recent change to the hypervisor exposed this race such that we now
sometimes lose it (where apparently we didn't ever before).
Instead read the hotplug script configuration during setup and use it
for the lifetime of the backend device.
The apparently more obvious fix of moving the transition to
state=Closed in netback_remove() to after the uevent does not work
because it is possible that we are already in state=Closed (in
reaction to the guest having disconnected as it shutdown). Being
already in Closed means the toolstack is at liberty to start tearing
down the xenstore directories. In principal it might be possible to
arrange to unregister the device sooner (e.g on transition to Closing)
such that xenstore would still be there but this state machine is
fragile and prone to anger...
A modern Xen system only relies on the hotplug uevent for driver
domains, when the backend is in the same domain as the toolstack it
will run the necessary setup/teardown directly in the correct sequence
wrt xenstore changes.
