The check for an empty lvb should check the entire buffer not just the first
byte.

The OCFS2 DLM allocates a number of pages for a hash to lookup locks.
There was a bug where a PAGE_SIZE bigger than the hash size (eg, 64K
pages) would result in zero pages allocated.

This allows us to have a hash table greater than a single page which greatly
improves dlm performance on some tests.

Gains us a bit of performance on loads which heavily hit the lockres hash.

The changes in the tty handling contain a bug while accessing
the last byte in the skb. Since special sequence for control of
DTMF and FAX via ttyI* devices handled via this path, these services
do not work anymore.

This file was created due to the issue regarding how to notify people
that devfs was going to be removed. Finally remove the entry as it has
served its purpose.

I've always found this flag confusing. Now that devfs is no longer around, it
has been renamed, and the documentation for when this flag should be used has
been updated.
Also fixes all drivers that use this flag.

This is the first patch in a series of patches that removes devfs
support from the kernel. This patch removes the core devfs code, and
its private header file.

This was spotted by coverity #id 1300. Since the array has only four
elements, we should just use those four.

This reverts commit c7b2eff059.
Hugh Dickins explains:
"It seems too little tested: "losetup -d /dev/loop0" fails with
EINVAL because nothing sets lo_thread; but even when you patch
loop_thread() to set lo->lo_thread = current, it can't survive
more than a few dozen iterations of the loop below (with a tmpfs
mounted on /tst):
j=0
cp /dev/zero /tst
while :
do
let j=j+1
echo "Doing pass $j"
losetup /dev/loop0 /tst/zero
mkfs -t ext2 -b 1024 /dev/loop0 >/dev/null 2>&1
mount -t ext2 /dev/loop0 /mnt
umount /mnt
losetup -d /dev/loop0
done
it collapses with failed ioctl then BUG_ON(!bio).
I think the original lo_done completion was more subtle and safe
than the kthread conversion has allowed for."
