Subject: linux-next: build failure after merge of the char-misc tree
Date: Mon, 8 Jul 2019 19:23:45 +1000 [thread overview]
Message-ID: <20190708192345.53fce4cf@canb.auug.org.au> (raw)

Hi all,
After merging the char-misc tree, today's linux-next build (x86_64
allmodconfig) failed like this:
drivers/misc/vmw_balloon.c: In function 'vmballoon_mount':
drivers/misc/vmw_balloon.c:1736:14: error: 'simple_dname' undeclared (first use in this function); did you mean 'simple_rename'?
.d_dname = simple_dname,
^~~~~~~~~~~~
simple_rename
drivers/misc/vmw_balloon.c:1736:14: note: each undeclared identifier is reported only once for each function it appears in
drivers/misc/vmw_balloon.c:1739:9: error: implicit declaration of function 'mount_pseudo'; did you mean 'mount_bdev'? [-Werror=implicit-function-declaration]
return mount_pseudo(fs_type, "balloon-vmware:", NULL, &ops,
^~~~~~~~~~~~
mount_bdev
drivers/misc/vmw_balloon.c:1739:9: warning: returning 'int' from a function with return type 'struct dentry *' makes pointer from integer without a cast [-Wint-conversion]
return mount_pseudo(fs_type, "balloon-vmware:", NULL, &ops,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
BALLOON_VMW_MAGIC);
~~~~~~~~~~~~~~~~~~
Caused by commit
83a8afa72e9c ("vmw_balloon: Compaction support")
interacting with commits
7e5f7bb08b8c ("unexport simple_dname()")
8d9e46d80777 ("fold mount_pseudo_xattr() into pseudo_fs_get_tree()")
from the vfs tree.
I applied the following merge fix patch:
