Add this to fix the following sparse warnings: fs/fcntl.c:280:22: warning: incorrect type in initializer (different address spaces) fs/fcntl.c:280:22: expected unsigned long long [usertype] *argp fs/fcntl.c:280:22: got unsigned long long [noderef] [usertype] * fs/fcntl.c:287:34: warning: incorrect type in argument 1 (different address spaces) fs/fcntl.c:287:34: expected void [noderef] *to fs/fcntl.c:287:34: got unsigned long long [usertype] *argp fs/fcntl.c:291:40: warning: incorrect type in argument 2 (different address spaces) fs/fcntl.c:291:40: expected void const [noderef] *from fs/fcntl.c:291:40: got unsigned long long [usertype] *argp fs/fcntl.c:303:34: warning: incorrect type in argument 1 (different address spaces) fs/fcntl.c:303:34: expected void [noderef] *to fs/fcntl.c:303:34: got unsigned long long [usertype] *argp fs/fcntl.c:307:40: warning: incorrect type in argument 2 (different address spaces) fs/fcntl.c:307:40: expected void const [noderef] *from fs/fcntl.c:307:40: got unsigned long long [usertype] *argp Signed-off-by: Ben Dooks Signed-off-by: Al Viro --- fs/fcntl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/fs/fcntl.c b/fs/fcntl.c index 3d40771e8e7c..7ca7562f2b79 100644 --- a/fs/fcntl.c +++ b/fs/fcntl.c @@ -277,7 +277,7 @@ static long fcntl_rw_hint(struct file *file, unsigned int cmd, unsigned long arg) { struct inode *inode = file_inode(file); - u64 *argp = (u64 __user *)arg; + u64 __user *argp = (u64 __user *)arg; enum rw_hint hint; u64 h;
