FTP services were shutdown some weeks ago, so the FTP URL
does not work anymore. Fix this by replacing it with
corresponding HTTPS URL.

The sample code was showing use of wait_for_completion_interruptible()
for waiting for an async. crypto op to finish. However, if a signal
arrived it would free the buffers used even while crypto HW might
still DMA from/into the buffers.
Resolve this by using wait_for_completion() instead.
Report
crypto_gcm_setkey() was using wait_for_completion_interruptible() to
wait for completion of async crypto op but if a signal occurs it
may return before DMA ops of HW crypto provider finish, thus
corrupting the data buffer that is kfree'ed in this case.
Resolve this by using wait_for_completion() i
public_key_verify_signature() was passing the CRYPTO_TFM_REQ_MAY_BACKLOG
flag to akcipher_request_set_callback() but was not handling correctly
the case where a -EBUSY error could be returned from the call to
crypto_akcipher_verify() if backlog was used, possibly casuing
data corruption due to use-
This patch set fixes various usage and documentation errors
in waiting for async crypto op to complete which can result
in data corruption.
Note: these were discovered in the process of working on a
patch set that replaces these call sites and more with a
generic implementation that will prevent t
drbg_kcapi_sym_ctr() was using wait_for_completion_interruptible() to
wait for completion of async crypto op but if a signal occurs it
may return before DMA ops of HW crypto provider finish, thus
corrupting the output buffer.
Resolve this by using wait_for_completion() instead.

Looks all right to me but I'm waiting for Maxime's review on these
patches.

Applied, we definitely don't want to have broken pointers. That said, I
have to wonder...does

Commit 4b4cea91691d ("mm: vmscan: fix IO/refault regression in
cache workingset transition") introduced three new entries in memory
stat file:
- workingset_refault,
- workingset_activate,
- workingset_nodereclaim.
This commit adds a corresponding description to the cgroup v2 docs.
Track the following reclaim counters for every memory cgroup:
PGREFILL, PGSCAN, PGSTEAL, PGACTIVATE, PGDEACTIVATE, PGLAZYFREE and
PGLAZYFREED.
These values are exposed using the memory.stats interface of cgroup v2.
The meaning of each value is the same as for global counters,
available using /pro
