Hi all,

After merging the staging tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

In file included from include/trace/events/erofs.h:8,
from <command-line>:
include/trace/events/erofs.h:28:37: warning: 'struct dentry' declared inside parameter list will not be visible outside of this definition or declaration
TP_PROTO(struct inode *dir, struct dentry *dentry, unsigned int flags),

^~~~~~~~

and moany more like this ...

Introduced by commit

47e4937a4a7c ("erofs: move erofs out of staging")

(or, at least, exposed by it). It needs, at least, a "struct dentry;"
added to the file.
