SRU Justification:

Impact:
If a cifs share is mounted in ubuntu-natty and we try to suspend cifsd
prevents the laptop from suspending.

Fix:
Apply f06ac72e929115f2772c29727152ba0832d641e4 cherry picked from
upstream commit (this is already in ubuntu-oneric) to ubuntu-natty linux
kernel.
This small patch allows the laptop to suspend even if a cifs share is
mounted.

Testcase:
Boot ubuntu-natty. Mount cifs share. Suspend or Hibernate. (This will
not work.)
Boot ubuntu-natty with cifs patch applied. Mount cifs share. Suspend or
Hibernate. (This works.)
