Merge branch 'for-linus' of git://git.samba.org/sfrench/cifs-2.6
Pull cifs/smb3 fixes from Steve French:
"Fixes for problems found during testing and debugging at the SMB3
storage test event (plugfest) this week"
* 'for-linus' of git://git.samba.org/sfrench/cifs-2.6:
Fix mfsymlinks file size check
Update version number displayed by modinfo for cifs.ko
cifs: remove dead code
Revert "cifs: No need to send SIGKILL to demux_thread during umount"
[SMB3] Fix oops when creating symlinks on smb3
[CIFS] Fix setting time before epoch (negative time values)

+ def_bool y
+ prompt "Enable seccomp to safely compute untrusted bytecode"
+ ---help---
+ This kernel feature is useful for number crunching applications
+ that may need to compute untrusted bytecode during their
+ execution. By using pipes or other transports made available to
+ the process as file descriptors supporting the read/write
+ syscalls, it's possible to isolate those applications in
+ their own address space using seccomp. Once seccomp is
+ enabled via prctl(PR_SET_SECCOMP), it cannot be disabled
+ and the task is only allowed to execute a few safe syscalls
+ defined by each seccomp mode.
+
+ If unsure, say Y. Only embedded should say N here.
