Hi all,

After merging the gfs2 tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from fs/gfs2/glock.c:39:
fs/gfs2/glock.c: In function 'may_grant':
fs/gfs2/glock.c:332:16: error: passing argument 2 of 'gfs2_dump_glock' disc=

Caused by commit

  9d0f1e82baf2 ("gfs2: Introduce flag for glock holder auto-demotion")

I have used the gfs2 tree from next-20211019 for today.
