Hi all,

After merging the ceph tree, today's linux-next build (x86_64
allmodconfig) failed like this:

net/ceph/messenger_v2.c:13:10: fatal error: crypto/sha.h: No such file or directory
   13 | #include <crypto/sha.h>
      |          ^~~~~~~~~~~~~~

Caused by commit

  cd1a677cad99 ("libceph, ceph: implement msgr2.1 protocol (crc and secure modes)")

interacting with commit

  a24d22b225ce ("crypto: sha - split sha.h into sha1.h and sha2.h")

from the crypto tree (and now in Linus' tree).

I have applied the following merge fix patch:

Subject: [PATCH] fixup for "crypto: sha - split sha.h into sha1.h and sha2.h"

conflicting with

"libceph, ceph: implement msgr2.1 protocol (crc and secure modes)"
