Hi all,

After merging the crypto tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

In file included from mm/zswap.c:30:
include/crypto/acompress.h: In function 'acomp_is_async':
include/crypto/acompress.h:124:16: error: implicit declaration of function =
'crypto_comp_alg_common'; did you mean 'crypto_tfm_alg_name'? [-Werror=3Dim=
plicit-function-declaration]
  124 |         return crypto_comp_alg_common(tfm)->base.cra_flags &
      |                ^~~~~~~~~~~~~~~~~~~~~~
      |                crypto_tfm_alg_name
include/crypto/acompress.h:124:43: error: invalid type argument of '->' (ha=

  124 |         return crypto_comp_alg_common(tfm)->base.cra_flags &
      |                                           ^~
include/crypto/acompress.h:126:1: error: control reaches end of non-void fu=
nction [-Werror=3Dreturn-type]
  126 | }
      | ^
cc1: some warnings being treated as errors

Caused by commit

  86464db929ca ("crypto: introduce: acomp_is_async to expose if comp driver=
s might sleep")

from the mm-unstable branch of the mm tree interacting with commit

  2beb81fbf0c0 ("crypto: remove CONFIG_CRYPTO_STATS")

from the crypto tree.

I have reverted these commits from the mm-unstable branch for today:

  86464db929ca ("crypto: introduce: acomp_is_async to expose if comp driver=
s might sleep")
  791f798331bc ("mm/zswap: remove the memcpy if acomp is not sleepable")

I will stop merging the -unstable parts of the mm tree from tomorrow.

Cheers,
Stephen Rothwell
