Hi all, After merging the akpm-current tree, today's linux-next build (powerpc ppc64_defconfig) failed like this:
fs/ramfs/inode.c:175:13: error: initialization of 'int (*)(struct
user_namespace *, struct inode *, struct dentry *, umode_t)' {aka 'int
(*)(struct user_namespace *, struct inode *, struct dentry *, short unsigned
int)'} from incompatible pointer type 'int (*)(struct inode *, struct dentry *,
umode_t)' {aka 'int (*)(struct inode *, struct dentry *, short unsigned int)'}
[-Werror=incompatible-pointer-types]
175 | .tmpfile = ramfs_tmpfile,
| ^~~~~~~~~~~~~
fs/ramfs/inode.c:175:13: note: (near initialization for
'ramfs_dir_inode_operations.tmpfile')
Caused by commit
5567a1a4b1c3 ("ramfs: support O_TMPFILE")
interacting with commit
549c7297717c ("fs: make helpers idmap mount aware")
from the pidfd tree.
I have applied this merge fix patch:
