Description of problem: shmget() fails on setting IPC_NOWAIT flag.
the programm fails giving error that EPERM ( errno = 1 ) for normal
user, and ENOMEM ( errno = 12 ) for super user.


Version-Release number of selected component (if applicable):
Kernel :2.6.0-test5_2

How reproducible:always

Steps to Reproduce:
1.write a C programm, for creating shared memory using shmget() with
IPC_NOWAIT as one of the flag.
2.Compile the programm.
3.run it. We get error
  
Actual results:gives error.

Expected results:It should execute and create the shared memory.

Additional info:
The same programm executes properly on other versions of linux(2.4.x).
When I gone through the source code of shmget.c
(/usr/src/linux-2.6.0/ipc/shm.c), the function newseg() called by
shmget.c contains a line 
if ( shmflg & SHM_HUGETLB )
     file = hugetlb_zero_setup(size);
is main culprit for the bug.
