*_get_inode_info() functions expect -EREMOTE when query path info
calls find a DFS link, regardless whether !CONFIG_CIFS_DFS_UPCALL or
'nodfs' mount option. Otherwise, those files will miss the fake DFS
file attributes.
Before patch
$ mount.cifs //srv/dfs /mnt/1 -o ...,nodfs
$ ls -l /mnt/1
ls: cannot access '/mnt/1/link': Operation not supported

After patch

$ ls -l /mnt/1

In smb2_compound_op we have a possible use-after-free
which can cause hard to debug problems later on.
This was revealed during stress testing with KASAN enabled
kernel. Fixing it by moving the cfile free call to
a few lines below, after the usage.

Move CIFS/SMB3 related client and server files (cifs.ko and ksmbd.ko
and helper modules) to new fs/smb subdirectory:
fs/cifs --> fs/smb/client
fs/ksmbd --> fs/smb/server
fs/smbfs_common --> fs/smb/common
