Hello,
(This patch is merged in 2.6.20 as commit
9185cfa92507d07ac787bc73d06c4eec7239)
With this patch, my desktop no longer powers off after hibernate(8).
It just reboots.
This user land fix can restore the old behavior:
echo shutdown > /sys/power/disk
The commit causes user land breakage

Hello,
Unexport __mntput() was talked about two months ago.
http://lkml.org/lkml/2005/6/9/69
Modules should not call __mntput() directly. If autofs or nfsd does that, it's
being wrong.

I think it is f = kmem_cache_alloc(filp_cachep, GFP_KERNEL); returns an
invalid pointer, then in memset(f, 0, sizeof(*f)); fault happens at address f.
eax == 0 is to clear the memory in memset().

Since 2.6.9, there came along the LOCALVERSION for people to add local
version in make menuconfig which was EXTRAVERSION originally for imho.
Now EXTRAVERSION goes just as a kernel version number, it's reasonable
to remove the `.' in its usage.
